Who gets to be anonymous and who doesn't? Cops or regular people? Mods or users? And there's the separation between public and private conversation too. Where do we draw that line? I had a post removed the other day. The moderator's identity (or psuedoidentity) remained hidden. Mine didn't of course. The conversation over his motive and actions remained hidden from public view too. And that seems bad to me. So ya, that line.
