You guys have to understand that bans and warns are all base on one thing. The user agreement that you accept or don't. Most games have the basic copyright issues and rules against using third party hardware or software. I must say I haven't bf:bc user agreement but I can say I've read s3 and resistances user agreement and not a single thing is mentioned about map glitches, lag, or rank up glitches. Maybe companies are learning but you can easily just email them saying that its not in the user agreement and they can't do anything. Now thats half true. Yes you did pay for the game, but not the servers. Its there servers and they can do ALMOST anything they want. So my tip is that you read the user agreement and see if it mentions rank up techniques. If it does then maybe you should think twice about hitting accept.
