Yeah I’m basically ignoring the part of implementing it as a separate issue from defining it, which is the part I’m saying is objective. Given a definition of what type of content they want to ban you should be able to figure out whether something you’re going to post is allowed or not, that’s why I’m saying it’s not subjective. Whether it can be detected if you post it anyways, would probably have to be based on reports, human reviewers and strict account bans if caught, with the burden of proof on the accused to prove it isn’t AI to have any chance of working at all. This would get abused, and be super obnoxious (and expensive) but it would probably work to a point.
