I suppose you get banned just for doing good as well.
Went 22-8 in TDM and when I went to log on, I was told my account was frozen.
Never used cheats on my account and was thinking about purchasing the hack from TMCheats, but with the anti-cheat system they have going for themselves, I don't think that will happen.
Will definitely purchase the bf3 hack from here though, once my new laptop comes in.
