The worst I've ever seen in 20 years is Horatio on the "Battlefront" forum on Ars Technica. The very definition of a "Little Caesar Bitch." He was Microsoft's Semper Fi Guardian, and an absolute cunt. He lobbied very, very hard for his mod status, and blatantly abused his power over anyone who criticized Microsoft in any way. I'm convinced he's really Steve Ballmer.
