AI asset usage in Touhou 20
« on: May 10, 2025, 01:08:53 AM »
Making a thread to centralize discussion on this and keep the main Touhou 20 thread clear for gameplay and other non-AI-asset-related chatter.

The Steam page for Touhou 20 went up today and it contained Valve's new required AI disclosures, for which this game has the following

Quote
AI GENERATED CONTENT DISCLOSURE
The developers describe how their game uses AI Generated Content like this:

Some background textures include Al-generated content.
There is nothing that is being generated live in real-time by Al.

So it's confirmed that the backgrounds people thought were AI-generated are in fact AI-generated. Probably some in UDoALG as well, but UDoALG predates Steam's AI-generated disclosure.

Just wanted to open the floor to discussion of how people think about this. I'll put my opinion in a reply.

Part of me is somewhat disappointed in this happening, especially since all of these years in the Windows era, ZUN has been using stock art from various art books and stock art collections, which gave the games a bit of a charming indie aesthetic. On the other hand, however, the backgrounds were never something ZUN made himself, it's always been something outsourced.

I've seen some chatter from people about how ZUN is supposedly super anti-AI, but I don't buy it. The full contents of those podcasts/interviews aren't translated, but my take is ZUN has always had a line he draws between what he wants to do himself and what to outsource, and the backgrounds fall on the not side. From his perspective, it's probably not much different, getting it from AI versus an artbook.

Also, according to this tweet, https://x.com/ryoya12951295/status/1919766666541490567 the poster for an event  that ZUN admitted was AI-generated was apparently generated using "clean" AI such as Firefly, which aims to not have copyrighted information in the training set. But there's also contention that Firefly isn't as clean as they're trying to sell it.

I am personally a pretty strong generative-AI hater, especially when used for synthesis purposes (generating music/art/text, as opposed to summarization and tweaking human input). I  think it's an affront to the creative arts, and I'm sad ZUN is using it. I don't think he'll expand his usage of it further than this, though, as the line between his work and outsourced work hasn't actually changed in this game.

This seems to be the most even-handed and comprehensive thread on the subject as of now:

https://x.com/richard_effendi/status/1921015276033741160

I'm still letting my thoughts settle, but if it's true this Firefly was what ZUN used (if indeed this was on purpose - the steam description makes it unclear if this was on purpose or accidental), it is disappointing but a sign that he at least intended to be "ethical." In my opinion, that means that it's a crime of ignorance, and one that can hopefully be addressed. But I am quite vehemently against AI, and if this remains in the full game I will be disappointed, no matter how much I respect ZUN as a whole.

Unrolled IceFairy's thread for people that don't have Twitter (thanks sorrowfulmizuki on Discord for unrolling this for me)

Quote
    Now that Touhou 20 is out on Steam and we have confirmation that the background does indeed use AI generated images, it's time to talk about Touhou backgrounds,  the GTP drunk stream, as well as ZUN's stance on AI. A thread.🧵

    Soon after the release of the Touhou 20 demo, there were questions if the backgrounds featured in the game were generated by AI, as well as discussion on the drunk stream ZUN had last December where they also discussed AI.

    Since the discussion was not archived and all we had was undetailed descriptions from a blog, I took the liberty of having someone ask around for more information regarding the stream, including the original writer of the blog itself, who has since updated the post.

    We managed to get some information in regards as how ZUN uses ChatGPT, how he generated the background for the poster, what sort of AI he uses and why.

    In regards to his ChatGPT usage, it seems to be the same type of use he mentioned in a SCoOW interview, not using it for art.

    For the background in the poster for the event if you look closely at the fractal patterns behind Reimu, the patterns are not consistent. It appears to have been created using either Photoshop or Adobe Firefly.

    As for why he decided to use AI for that, it appears that it's because Adobe Firefly is (supposedly) trained using only their library of stock image and public domain materials, making it simply another source of stock image to draw from.

    It is well documented that Touhou backgrounds make extensive usage of royalty free stock images, whether from reference books, asset packs, Wikiedia, or even Deviant Art.

    So since he already uses stock image he didn't make himself for the background, Adobe Firefly provides him with a quick way to get illustrations for backgrounds without needing to spend too much time searching all over the internet.

    As for ZUN's stance on AI.

    Personally, I don't believe his stance is "AI is abhorrent", but it's not "AI is the future", either. It's simply that "AI is not a creative tool, but one for economy and efficiency".
    Whether you think this makes his usage ok, that is up to you. I think it's ok if you're upset/disappointed and wish to no longer support the series/ZUN. But I also think it's ok if you're not bothered by it, as well. I don't think either reaction makes you more or less of a fan.

Wtf that's genuinely a strange move for ZUN. I tend to believe that you must do honest work to get honest earning, and in my perspective, using AI isn't an honest work; it's slimy, used by lazy idiots who don't even lift a finger to work to earn money. I am really mixed with the idea you can use AI for commercial product, as it means you use a generative robot to do that stuff. Hopefully he fixes this, because I feel this could be a bad thing in the future.

Boooo, gave the guy the benefit of the doubt on this one but honestly kinda disappointed on the reliance on AI for a main Touhou game

Now the usual stock image being royalty free (meaning nobody missing out on any cash monies) plus background images generally being a little more than flavor bonus means that there's no real harm nor the like here, but the concern for me is how much of a slippery slope AI can be. Technology will only keep on improving, and AI capabilities will only grow up more and more. What if AI gets to play a more prevalent role in the future ? Backgrounds generated off already royalty free stock images is already pretty borderline to me, and that despite how minor it is, and I hope it's not gonna get worse in the future. It would feel a bit deceptive if large chunks of my favorite magical girl series turns out to have been made by some soulless robot instead of my favorite drunkard, in the future.

There are places where AI can be relied on, and places where its help can make breakthroughs, but I don't believe creative / artistic endeavours are part of that.  Normalizing AI use in creative / artistic endeavours is a suspicious slope of questionable slipperiness that I don't think creators should want to find out. I hope that ZUN'll backtrack and even go through the trouble of finding vaguely fitting background art despite the trouble, if its just to make a purely symbolic statement.

Nah, I wouldn't worry about tracing that he hasn't done in decades nor have bigger implications

The most important parts of the game + characters are handled by ZUN, but the willingness to rely on AI can be worrisome for those wsho don't really like it : it's only minor backgrounds for now, but I hope it won't be more for the future : like, Mr AI model, can you draw me a 2hu or design my game ? Stuff like that.

I honestly can't say I care too much whether or not he's used some AI-generated assets. I'm in the camp of thinking AI overreliance (and overreach) being a bad thing, and agreeing with the view that AI should never replace human creativity in a professional capacity (especially as it harms the job market), but when it's being used in an indie title for visual purposes, and doesn't infringe on someone else's work, I don't think it really matters. ZUN seems to have used it responsibly and for its intended purpose. Slippery slopes are one thing, but I have enough faith in the man that it doesn't detract terribly from the game for me. He's more or less just doing what he's always done, as has been said.

Mr AI model, can you draw me a 2hu or design my game ? Stuff like that.

See, that I feel is everyones biggest concern, and in my mind feels unbased.
ZUN may be fine with using ai to create or find images to use, but he still thought up the locations himself. And even more so on 2hus and game, the main things he wants to do.

I just couldnt ever see ZUN handing the reigns of working on and creating stuff over to ai, in that interview where he talks about his usage of ai he says that he found image generators really boring and that he would rather make something himself, and thats just images; ZUN puts a lot of care and time into the characters and story because Touhou is a personal thing to him. People are justifiably paranoid, but to me as long as ZUN still has the creative spirit hes always had, he will always want to make stuff himself.

Besides, to me this is a really low offense, literally just textures and images; people are acting like ai ruins the magic, and yeah sure ZUN probably didnt have to manipulate images as much and people like that stuff, but reiterating that all this stuff was still thought up by him, not an ai, and there was still work from him too.

He didnt ask ai to make him a pyramid, he asked ai for pictures of rocks that he then made into a whole stage that goes from cliff into pyramid from, see the difference? He himself made a spinning pyramid model, not an ai. He himself made that shot of going into the cliff, not an ai.

As for how it affects my view of the game? It doesnt, because to me the whole ai image thing is its own separate thing, and has nothing to do with how I should feel about the game; I cant fault the game and I dont really want to fault ZUN, but the blame does go to him, the game gets none and shouldnt have to be vindicated.

I am being very optimistic, and frankly I wish more people would too. Do what Dutch says:

Have some goddamn faith

Oh trust me, I know all about the issues with PoDD. But I'm also not in the business of holding against someone something dubious they did 28 years ago for a game that sold maybe 200 copies in its lifetime. My hopes are simply that if ZUN did indeed use AI, even supposedly "clean" AI (and Firefly sounds like it still has many ethical problems even if it is technically not stealing art), he'll change his tune with time and grow from it, just like he stopped improperly using assets after the PC-98 days. It all comes down to how he responds to this, imo.

Lets be honest, the ai images already present are not going away, ZUN has a history of not touching things in demos and i dont think the backgrounds are something that high on his list, even if we yell at him.

We can only hope that the rest of the game doesnt have any ai images, but dont get your hopes up.

Which is at least partially the reason why so many people don't even want to consider PC-98 games canon anymore.

The issue with AI art here isn't even a legal or moral one, though that's enough for some to go up in arms. It's that it stands out clearly enough for people to have identified it from day one. And it's one of the things that are so uncanny that you just can't unsee once you recognize it. And let's be real here, was there any reason to use AI in the first place? If it's trained on stock and free art anyway, why not use THAT, just like before? Nobody would mind if old assets were reused either.

The most troubling thing about AI usage is that it's not character art or music that's next on that slippery slope. It's bullet patterns. Maybe not for spellcards, those have to be thoroughly thought through. But I feel there might be a strong temptation to leave stages and nonspells to a hands-off approach. Which can end up feeling no different from procedural generation, and might get to the point of going through untested. Not like ZUN's manual balancing was nearly thorough enough in the past, but potentially relying on AI for that would be a scary new low.

I'm not too worried myself. I imagine he'll keep to just expediting what he used stock assets for already. I don't really see him relying on genAI for bullet patterns aside from quick reference or something along those lines. I find it unlikely he'll allow it to detract from the parts that matter.

Idk some people have gotten annoyed at how often forest.png (tm) was used in lolk, hsifs (twice I think?), and UM lol

It's bullet patterns
How would that work? There's a multi step process there that I'm pretty sure current AI's can't handle or would give really obviously terrible results doing. Especially since ZUN uses his own scripting language for patterns, for which there is no training data.

I've been defending ZUN and him not using AI while these rumours have been going around and it being revealed that he does use AI was a pretty big hit to me.

As CyberAngel said, all of this is just unnecessary. Unless ZUN has been living under a rock for 2 years then he should obviously know that using AI to any degree in a work is controversial. So why even do this just to save like 2 hours of extra work on his game. If ZUN thought that saving time was a bigger priority over potential ethics problems and dissatisfying the fanbase then that worries me over the mindset he might be starting to develop as time goes on which many people here have already elaborated on.

And if we assume that UDoALG also has AI content then it just further proves that ZUN doesn't really care and that he only bothered to be public about it because Steam made him. If he did actually use AI for UDoALG then he should come out about it or else it ruins the point of being "public" about him using AI.

I highly doubt he's is going to suddenly have an epiphany regarding his actions and attone for his mistakes. The only way I can ever see him changing this is if some boycott or protest happens and ZUN doesn't care about us westerners so that leaves the Japanese Touhou players. And while I don't know what the stance of the average Japanese Touhou player is, I would like to assume that since doujins are a very important aspect to Touhou, that they appreciate the personal efforts that go into art and are against AI, but to be fair I also thought that way about ZUN and it turns out I'm not as right as I thought I was. Although correct me if I'm wrong, I can't really recall any times where the Japanese Touhou fanbase have decided to band together in order to have ZUN change something in the games.

I can understand the point some people make about it being such a minor thing to worry about and that it was already content not made by him but this just leaves a really bad taste in my mouth. This situation is absolutely pointless. Funnily enough, it could have all been avoided if ZUN just decided to put an extra hour into his work.

From what I know, that scripting language is not much different from the usual code, so a specialized coding AI probably wouldn't need that much effort to set up compared to a completely custom language. As for training, he should still have the data from 18.5 and UDoALG  :meiling:

The person behind the previous Twitter thread posted a follow-up explaining the nuances of ZUN’s decision.

https://fxtwitter.com/richard_effendi/status/1921213802495828468

I pretty much agree with this. One has to keep in mind that AI’s presence in the western world is quite different from how it is viewed elsewhere. And ZUN electing to use it in a single part of game development where he already makes use of stock assets and spends a long time searching for the right pictures to tweak, it will expedite the process that much more to allow room for working on the parts he enjoys more. Especially so when he tries to avoid burnout.

Ahem, hello, some people here, I don't really find the reuse of old assets to be that bad since ZUN generally adds extra flavor anyway. It's acceptable and understandable (and a very indie & doujin game design philosophy) that a one-team small developper would reuse functionnal assets that they already have for whatever work they'll do, so also OK despite seeing Reimu's same old back for decades or even freaking IN sprites in decimal games : unneccessary new innovations would only take away from the limited time, energy and ressources of small devs. Heck, even TH15 makes a random reuse of a TH12 lotus pattern image, and you'll need to dig extra hard to find less than a handfull of people outraged there.

What's hard to imagine for me is how hard that process of looking up an image can be. Here's an immediate example : google up "egyptian background motif stock image royalty free" and boom, https://www.shutterstock.com/search/egyptian-motifs, plenty of fresh choices off of shutterstock : a bit inconceivable that the search would take a lot of time in light of this, so the efficiency argument falls apart to me. Even in game, due to the additional shadowy layer, bullets + movement of the background, you wouldn't have the leisure to identify and process whatever's in the spellcard background, meaning that whatever flavor ZUN's trying to go for with AI isn't adding much. So going the extra mile to experiment with AI generation is just hard to understand for me, cuz as things currently stands, it's a decision that only invites controversy and worry.

Now the "acceptable" boundary for AI use in my mind has been set to "miscellaneous backgrounds", and I hope these suspicious AI experiments won't push them further back. All work is tedious anyways, and once AI's capabilities as a tool evolve to be able to undertake more complex tasks, who's to say what other "expeditious work" it'll be used for, if efficiency is the main consideration ? I'm trying to have faith, but this is overall an unpleasant pill to swallow. I hope we won't get more of these for the full release, just as a purely symbolic statement.

Well, even by this point we still dont know the exact reasoning why ai is being used, so until that comes out we can only speculate if any of it will go further.

Also, bit odd, but gratitude over how everyone is handling this, were doing pretty good at being civil and even though ive seen plenty of people be disappointed theyve all been very understanding and respectful, honestly it feels like a commodity at this point and im glad that we could deliver well.

What do you expect from a doujin work? I expect something that the author would put a lot of work into every aspect of purely out of love for the artform. I expect something that I can go into every detail of and know that it's a conscious decision by the author that they might have spent a lot of time on. ...This might be an idealistic view that might not even be true a lot of times, but I still believe it's an ideal that best embodies the doujin spirit. I don't think it's wrong for doujin authors to use means that would help them in making their works. However, I do believe that any usage of AI generated content is a step too far from that doujin spirit. You can no longer be sure about how intentional any details in such a work can be once that enters the picture. And that takes away A LOT of enjoyment you could have from such works.

One has to keep in mind that AI’s presence in the western world is quite different from how it is viewed elsewhere.

I just think he isn't as "online", like the kids say, as most of his fans.

Oh really? Well, why don't we let them know about it then?

Here is what I suggest to anyone who has an issue with this matter. Once the game comes out on Steam - buy it, do a single run (or just listen to the music test), then refund it and leave a negative review that mentions your feelings on AI art usage, preferably in English AND Japanese. If you want your voices to be heard, I can think of no better way.

And if anyone thinks this is going too far - it's best for fans to put their foot down this early before AI usage goes much further than that. Even if ZUN himself won't go beyond using it for background textures, other doujin authors might see that AI art was taken well, most likely without bothering to go into details, and use it themselves in much more invasive ways. If they need "AI=bad" hammered into their heads then it's worth doing so as soon as possible.

Like I said, the second Twitter thread is a pretty comprehensive explanation of how this situation may have come to be.

EDIT: ZUN already doesn't create his own background assets, simply editing what he can find to best suit whatever intention he has. So in so far as how this affects Touhou specifically I don't really think anything changes just because he's made use of Firefly for this aspect. Even when using stock images, he clearly has had some specific vision of how he'd like the visuals to be that he spends time working into the game to the point you rarely notice that they're things he's found on the internet. As far as I can tell, Doujin has always been a bit loose with how assets are used in developing a game anyway.

As for how this might affect other Japanese developers? Who knows. As Icefairy outlined, Japanese media and communities don't have the same associations with AI that English-speaking communities do, so it is very possible it will become easier for Japanese developers to rely on it as a tool. Though I can't imagine Western gamers would allow for egregious cases to pass. It would be a real speedy way for the developers to become a laughingstock among them.

I'm kinda indifferent so long as the overall quality and the creative efforts remain as is through the intentions of the developers. In one-man shows like this, anyway.

Personally speaking, I don't really think review bombing would have the intended effect, most of all because ZUN is a person and not a corporation (also, recall that until six years ago there was no market to sell to the west at all and he got along fine without us). If this arose due to a misapprehension about a certain AI generator being "ethical" to use, then I think showing him why it is a mistake would be much more likely to have an effect - though it's foolish to think the average person would get a one on one chance to convey this.

At worst, he'll see the outrage as a cultural difference and write the complaints off without looking into them, maybe even distancing himself from this side of the fandom. Remember that we are a periphery of the greater fandom, and if you actually want to make a positive impact you should try and engage with that in mind - and I don't think a distinctly western tactic like mass review bombing is going to be what does it.

Really, for the time being there's nothing to be done but hear from him how this came about and why. I'm guessing the monthly Touhou Radio near the end of the month is when this is most likely to happen.

Well, just sitting there and not buying the game will definitely accomplish nothing. That is way more likely to be written off as more fans just getting bored of the series. And it's not like I'm saying everyone should do it. I don't think even everyone who has an issue with this joining in would be able to move the needle much from the usual "Overwhelmingly Positive" rating. But if there's even a slim chance it might get the message through then I believe it's worth to do something with the game you wouldn't play anyway. Otherwise, well, don't come crying if things get worse in the future.

I would like to say some words about this topic. I just wanted to briefly summarize the information about this topic.
I suspected that ZUN was using AI since the first suspicious backgrounds were extracted and I have been observing what was happening in Western and Japanese Twitter.
I think you know the situation in the West. The attitude towards AI in Japan is different from the West. For now, in Japanese Touhou community there are three main points of view on this topic: "supporters" (pro-AI/don't care much about AI), "moderate" anti-AI (against AI, and may not like the fact that ZUN uses it; but using it only for backgrounds is acceptable) and "hardline" anti-AI (against AI and hate the fact that ZUN uses it). It is hard to say the actual size of each group, but since the beginning "supporters" were the most vocal, recently "hardline" anti-AI tried to be vocal (but they just mostly showed that? yes, they exist; but anyway they gathered some attention).
About ZUN's opinion on AI it is much more complicated than just "that radio broadcast in December". He already had some interesting views about AI around WBaWC release in SCoOW. There were some other later statements about AI like "things that can already be made by AI can be left to AI" and "it would be better if AI spreads" in 2023 + he already insinuated that AI reduces the amount of work required around UDoALG release; but at the same time he said that value of things made by humans themselves would increase.
About AI and Doujin. First of all, takes about copyrights wouldn't be taken seriously. Next, AI is already allowed (with or without limitations) on many Doujin events (including Comiket and Reitaisai (and I wrote about that several months ago)). The question "what is a doujin thing and what is not" is difficult. There are many things which are normal in Doujin now and which were no-no many years ago. The Doujin scene hasn't fully decided yet if AI is acceptable or not, there are different opinions on this topic (for example there are people who want to ban AI on Comiket).
What actually disappointed me is how Westerners reacted (I am not talking about the point of view but the reaction itself). I understand why many Westerners are against AI. But it looks like they don't learn from their mistakes. You should know that Japanese fans would protect ZUN. But I don't understand why many Western anti-AI decided to directly confront ZUN. The reaction of Japanese fans is obvious in this situation. Maybe it is a better idea to change tactics? Being overemotional won't help. There is a thing about ZUN using AI about which even many Japanese "supporters" would agree that it is a bad thing. The problem is that many Westerners don't care much about that and not fully understand it. I think I gave enough hints.
I hope this information was useful.

The japanese side who gets to interact with ZUN at various conventions might find him more personable cuz they get to interact with him at real events, so I'd get why they'd have discussions about him in a more understanding way, while most of those overseas (not just the west) don't even get to meet him but experience his work and appreciate all the things that have derived from it : he can pretty much be considered to be a symbol of something else that the regular corpos and entertainment industry doesn't provide rather than just an individual tbh, and the faith and goodwill that ZUN has acquired over the years is getting heavily tested cuz of this recent AI thingy.

Besides, there is something that should be reminded, the crux of this discussion, despite all these interviews and work time reduction talk : we have a very REAL use of AI now, and its for at least a SPELLCARD BACKGROUND. Like I previously said, finding some random stock image can't be that hard on the internet : it's just a matter of handling search engines. Furthermore, the background being hidden behind a shadowy layer + the actual game and its bullets also means that it wouldn't be the priority as far as the player's attention goes, and therefore shouldn't need that much thought from ZUN : we have HUNDREDS of spellcards over the years, how many of their backgrounds do you distinctly recall by memory, without searching for them separately ? The notion that the search for such or such background would take a lot of time therefore seems too unrealistic to me, even moreso if its to be used for a spellcard ...

I would be willing to show much more understanding if the justification was that there weren't satisfactory stock images that could be used as textures for such or such stage background or 3D model, or even to avoid having to put extra work like for the Makai backgrounds brought up in the twitter threads, at which point using AI for getting more customized results would be much more efficient and understandable, but the reality of it is that IN PRACTICE, AI generation WAS USED FOR A SPELLCARD BACKGROUND (that you wouldn't even get to pay much attention to in-game), of all things : was there a serious need to use generative AI even ? How much time would having the AI model generate images over and over until something "satisfactory" came out realistically save, compared to just grabbing some stock jpeg and slapping it in game ? Cuz if its something minor but already requires AI assistance, then its a pretty unflattering look. Besides its not like AI is a guarantee of quality, if you look at the inconsistency plus lack of symmetry in the generated background.

Besides, the justification of AI use is honestly a matter of rhetoric anyway : there will always be arguments to make it sound either good or bad. For me and some others, it's the question of principle (+ where AI will go in the future of this series) that is the worry, not just "duUuUh AI Le bAd, EveRybOdy sAId soOoOO" (the legal, moral, ethic concerns that people bring up can't just be dismissed either). ZUN is not just some other doujin guy, he is the top dog as far as touhou doujin goes : there's the respect and admiration he gets from doing his one-man-team thingy + hard work for so long, plus the fact that wherever he publishes his work, fans can just put theirs as well, meaning that he pretty much determines what's gonna be normal or not : if ZUN gets confortable with AI, what about everyone else, does it become fair game too or will we need to wait until proper limits get chosen for AI use ? Can Tanaka from Tokyo just generate his TH doujin and say that its just a tool that helps his vision be brought to light quickly, then occupy a real physical space in Comiket to sell it ? Is the artistic merits of AI scripting + AI being the messianic tool that bring the art to the masses gonna become a valid talking point going forward ? These are obviously very extreme examples, but kicking the floodgates of AI open brings a lot of additional considerations and concerns, and clear boundaries are gonna be needed fast. Also it's not about doujin in general, it's about touhou doujin and what will fly here, going forward (Buncha stuff restricted in Touhou guidelines is OK for general doujin anyway).

There's definitely a no-AI purist attitude in play as an excacerbating factor in this AI debate here, but regardless it should also be said that the contributions of various creators is not only Touhou's lifeblood but also what made it what it is, and their involvement is not just because of appreciation of various aspects of the series but also ZUN, the creator : AI already puts artists on edge these day (you'll see the odd "not to be used for AI training" in artworks occasionally), due to reason that's pretty much talked about, not to mention the various people who increasingly beccome less favorable to AI due to various reasons.

At this point, I pretty much expect AI generated backgrounds to be a mainstay going forward, but I hope AI (specifically generative AI) and its acceptable role get properly defined boundaries soon-ish, and doesn't get to play a more prevalent role in the future. Anyway, realistically, I think that the reasonable expectation for AI going forward is that it won't to play a much bigger role in the creative process, but at the same time, the willingness to rely on AI has already made its mark, hope it doesn't encroach in the wrong places ...

But I don't understand why many Western anti-AI decided to directly confront ZUN.

Did someone send him a package with something nasty or dangerous? Because THAT'S a direct confrontation, and definitely not acceptable. Voicing one's disagreement with methods used in a work's creation is a right that every fan should have. And doing that in a quantifiable way by officially available means at a place visible to everyone would be the best way to settle this matter.
