Stories and art are on a case-by-case basis and kind of a separate discussion. We allow people to post things that might be over PG-13 as long as they have warnings, but still nothing overly sexual or gory is allowed. Yes we are limiting people in that way, but there are plenty of other places to post your stories if those are the kinds of things you want to write about. It's not just kids that don't want to read those kinds of things. They make plenty of adults uncomfortable too, and this is supposed to be a safe, friendly place for everyone to be able to enjoy.
