I have also been banned for no actual reason.I have tried making a thread.Still no answer.I have also sent e-mails to Treyarch and Activision but still no answer.I really hope we get our accounts back,because we spent all that money to buy the game.I also bought myself personalization packs,so I don't want them to be wasted.I hope the can do something about these bans that happen to no reason.Good luck.

You can read the response that one of the moderators gave to a thread regarding bans. Here's the link: I Got Banned And I Don't Know Why
