Meh, if you want to hack without consequences, go to one of the earlier versions of Call of Duty. Back in the days when I played Modern Warfare 3 I would hack all the time and never got banned, I got recorded/reported and still not banned from it
I didn't get banned from this but got a reset because my account was "corrupted". I think that this is not a reason to ban someone but just to reset their account? Either way I'm using it now and haven't got a reset yet again.
