IIRC, the coders are working on a NOT filter as ratcreature suggested.

And yeah-- there's a lot of unusual tags out there, which is fine (and sometimes hilarious). But those tags add to the size of the archive and the possibility of ambiguous tags (like "Apollo" and the like) that a user might sift through.

And honestly I'm not sure what my own position is, so poke away! (I do feel strongly that working on functionality for non-writers is really important, but that doesn't mean I hate original fic.)
