Thank you for the feedback! This is very thoughtful! I have some additional perspective for you.
"The thing you describe does not verify that something is human made or ai made."
That's correct! The goal of the tool is not to replace human judgment with machine judgment, it's to scale human judgment.
"This will not catch retweets of questionable posts or any other kind of social media sharing."
Yes it will! The signer's metadata travels with the content unless deliberately removed, so if you, a person I trust, share something signed by a person I don't, it won't register as verified and it can be marked or filtered out at the application layer.
"So if you want this to fly on social media you have to prepare for that"
No I don't! Social media platforms all already have account integrity programs, there's no need to invent my own. Also, see immediately below.
"And if you regularly have to remove bad actors, the whole concept of trusting the posts of members of the network is made obsolete."
But you don't have to! A bad actor making an account must convince others to mark him as trusted and stay that way. If someone is going around marking shady accounts as trusted, other users will remove that enabling user from their trust network by removing trust links or adding distrust links. Assuming selfish behavior for every user, the trust network heals itself. You can make 10,000 fake accounts, but without getting others to mark you as trusted, it gets you nowhere
"For game publishers, if you use the concept of trust, there is just that. You do not need an added layer of tech for that"
Sure you do. Trust, but verify. Would you pay a credit card bill that wasn't itemized because you otherwise trust the bank? Would you pay for a meal without looking at the receipt? We add a tech layer to trust all the time, you're just so used to them that they're invisible to us.
"If you find proof that someone is lying, report it to Itch and let them deal with the fraudster"
...who will promptly change their name or account and go on defrauding people. If trust follows you, reputation matters.
"If you need trust in the actors, just trust them to not tell lies about the ai status of their creations."
'Trust be, bro' doesn't cut it anymore. We're past that.
"And using such a method for ai games, is just overengineering."
It is not. In fact, it's designed to be nearly transparent; if the software you're using knows how to read the file format, the end user and the creator have to set it up once (5 minutes) and never think about it again. That's the beauty of computers.
"The developers describe how their game uses AI Generated Content like this:"
Sure, but that's just Trust Me, Bro. How much of it is AI generated? Can you verify that? Which voice actors provided which lines? Did you notice the AI-generated content that sneaked through QA in Claire Obscure? You know what would have caught it?
