Question moving jerkoff bragged here last week he had "99 other IDs" when I busted him and blocked one. Why does yahoo answers let users?

...like this ruin the board and make it unusable for other people?
Update: I actually don't think he's political, he has mental illness like Aspergers and has to come here and move every thing around to satisfy his Rain-Man like obsessions and impulses.
Update 2: I just busted a "Jake" posting on my other question, who moved it. I think that's one of CMJ's many ID's.
Update 3: This question has been moved about 25 times so far.
Update 4: This question has been moved about 25 times so far.
Update 5: All in all he's moved my questions about 100 times today. Is there not some filter that can take care of this?
Update 6: All in all he's moved my questions about 100 times today. Is there not some filter that can take care of this?
