While I am aware that every single SE site must enforce and follow the CoC guidelines, and the fact that each site has slightly different site-specific rules to suit their needs, I have been wondering something for a while. Does every SE site have different guidelines for questionable content too? I asked this because, ever since joining the Anime/Manga SE site, I've seen a lot of questionable messages AND images in the Anime/Manga SE chat.
To the point that I was wondering if I should flag said messages and get a moderator to see this, because even though the chat is dedicated to anime and manga, there's a clear distinction between that and ecchi/hentai. And yes, many anime/manga tend to blur that line and that makes moderating a site/chat like that even more difficult, but even so, content like that is sure to get you suspended from other sites and their chats, and not just because it was off-topic.
So my question is very simple, do we have different guidelines for stuff like this? Should a site such as that have stricter guidelines for the issues mentioned above? And should I (or any other user) flag for moderator attention if we see content such as that?
