It is mentioned here, where no one reads. https://itch.io/t/4309690/generative-ai-disclosure-tagging
The disclosure has 4 buttons and the "no-ai" filter lumps all of them together.
You can specifically search for it positively. https://itch.io/games/tag-ai-generated-code
I wish for a "no-ai-content" filter and a "ai-generated-content" filter which would only bunch text, images, music together how it is currently written in the faq , since I think it would better reflect the prefrences of users.
