As far as I know, we haven't been targeted yet, but it's their sworn mission to purge the entire site of anything considered "pornographic" by their very stringent standards (which don't necessarily match ours, of course). The site is big, so they've got their hands full, but from what I understand, they've got a spider algorithm that crawls the site looking for fics that fall under their "unacceptable" umbrella, and alerts them. Last time I looked, they had to actually manually enter the fandom category before it would be able to do anything, but all that says to me is they haven't got to us yet. I think they are targeting kid-friendly fandoms first, like Pokemon. Just my guess...
