Yes, I understood what you meant. Yes, people should preface their stories if it deals with more mature subject matter still within the TOS (for example - drug use). But we can't make something like that obligatory unless it is for a clear cut thing (for example, inter-species relationships). Different people have different tolerances for things like violence and sexual encounters. And while we do make sure there is a clear "this is too much for these boards" point, different people have different levels with what they are okay with. If you don't like where a story is headed, but it is still within TOS limits, just don't read that story.
