I agree. Sometimes people replace their comment text with "[deleted]" or ".", which is already abusive when the comment has replies. But this is the worst case I've seen of someone rage-editing to gut a thread.

I've restored the penultimate content of each of the posts that they overwrote that way. There remain 5 (including the GP) which just say "Yeah, if I'm just gonna be down-voted [etc.]" but that is because they were posted that way and never actually said anything else—which is a whole other level of abuse in its own right.
