There do seem to be a lot of peole being banned for no reason. It looks like it might be connected to using controllers with back paddles like scuff or Ellite. EA refuses to provide any info, there are quite a few people on this thread.

To everyone who can only respond with "you must have cheated, I've never been banned", that's what we all thought. I've played every BF game have a 16 year old EA account and am a 42 year old gamer dad who has no interest in cheating and just wanted to play with his son.
