I'm reminded that one of the first lessons I learned as a forum moderator in the early 00's was "some people only want to know who the targets are". Doesn't matter if the rules are "don't be a dick", seventeen pages of legalese, or anything inbetween: there are always folk who really, really want to hurt someone. When told to stop they just want to know "if I can't hurt them, then who am I allowed to hurt? Must be someone, surely."
Sometimes I stumble across a particular species of queer discourse post on this site and I get a vivid mental image of the OP paging through an enormous rulebook with furrowed brow muttering "come on, there must be someone I'm allowed to be homophobic to".
