Well, I've got a filter for "kink" (mostly scene reports and the occasional fantasy or TMI regarding my sexuality or BDSM).

I've also got an "erotica" filter, which is strictly for fiction. I made it seperate because the two biggest "works in progress involve underage characters which makes some folks very uncomfortable, even if they are doing stuff with each other.

And I've got one I haven't used much that's for posts abuse the stuff I went thru growing up. It's labelled "abuse" which should give you a clue.
