If someone posting a story that was created by AI wants to put a indication in the title or early on that should suffice. If they do that you either don't click on it or don't waste time reading it .since it was stated early on.
Practice has shown us that no matter how clearly we explain a rule people will use it to try to move stories they don't like off their favorite section. And ai generated is a wide range. There is ones entirely by AI, ones who used AI to help certain parts. And most importantly, I know if we created such a section we would get there type of reports
"Clearly an AI story" "yet another AI story" Another AI story why the hell aren't these being moved" when there is no indication they are an AI story.
So yeah no Ai section.
