I'm seeing a whole bunch of posts under rating:s nipples. It says on the ratings help page that nipples should not be rated S.

So are those images wrongly rated, or is there a sort of exception? Like male nipples are allowed?

@Kemono-Kay: male nipples are definitely allowed in most cases. The female ones rated s seem to mostly have them visibly present but behind clothes, which might be more of a blurry case.
