EA has informed the Twitter world that they have started banning players in Battlefield 3 that are exploiting the game. Most of the bitches cheating are boosting their XP using methods like the one below. Now, I am showing you this, but I'm suggesting that you DO NOT do this or anything like it because you will probably get banned.
EA has banned hundreds of players and that number is sure to grow into the thousands. They are banning players and wiping their stats completely! So think twice before trying this or other exploits like the one above. They are however, also working on a fix that won't allow this to happen at all.
