Furry is my easy pick. He isn't as bad now, but picks his battles more wisely. The Spank me kid was pretty bad too, but never actually had the "I know all....you idiots must cower under my dominance" air to him, while not actually having accomplished anything. This, combined with the (at least) 3 seperate petitions I saw to have Furry banned posted on multiple conference message boards, makes him my choice.
