Apparently EA bans you for being above average at their game...
I have no idea what grounds they had to do so, but I got banned for "cheating" after only two days.
I'm, at best, a +2.0 KD player. That's well beyond the average, but by no means anything close to suspect on PC. And there's no way they could detect any sketchy third-party software, as I have to run nothing else in the background just so this game can have all of the resources it so desperately needs.
Honestly, it's shocking how much they've dropped the ball on this one. The game feels like one big panic button, and they've been slamming their fist on it the entire time.
If you can't distinguish the skill gap between players -- better yet, if players are going to abuse the "cheating" report and cause the system to pull the cord, no questions asked -- then you have a flawed system.

EDIT: Enough people have confirmed the same "cheating" ban here, so I made a post on the "Bug Reports" forums. Be sure to boost that one so this issue gets attention, and remember to specifically file a bug report at EA help -- bans can take months to appeal.
