This could be true, but I think some would want him booted. He is hogging the kills, and it ruins the game. Most people realize this.
And so far, there aren't any multi-player cheats, and I can't imagine that any will exist anytime soon for PS2. With PC, that threat is more real, I suppose.
The real need for booting is team killing. I played a couple hours today, and games were plagued by it. Votes were constantly being called, but nobody got kicked.
