@Lauda: Is there anything to do about the alt spammers? Can they be nuked, or is this not enough? If they can be nuked, I can go through the hassle of making a much longer list. If not, I'll save myself the time.
If one can acquire evidence that they are all linked (besides the obvious, which is circumstantial), then yes. I'm inclined to nuke them all, but there isn't adequate evidence to do so. Therefore, I'd advise you to open up a thread in Meta regarding them.
