LOL. it's no secret. some Japanese guy got the ban hammer earlier this year for doing the same thing. PM this info to cog or EvangM.
LMFAO. these guys can't just quit games to fake their stats anymore so they resort to this? wow, no lives and super dedicated to faking stats on a video game. I guess they really, really, really want to be well known and thought of as e-cool for a fake KDR. LOL.
ps. for those that don't know the trick, these are actually 3 friends all playing split screen with dummy accounts as team mates. They all enter matchmaking at the same time to be matched up against each other. Each of the 3 guys just run around killing the idle dummy account of his buddy to boost their KDR.
that's what they're doing. I don't care if everyone knows how to do it. go ahead.......but you'll get banned for it. If you feel like wasting all that time (time you could be spending talking to a girl or something) have at it....then lose your ability to play U3 on that account when you're banned.
