why

what did you do ? to get banned ? or with tool you use ?

just use BO4 Zombie Trainer ，i dot konw why

That'd probably be why then. There's always a risk of getting banned if you cheat, we all know that and the post for the trainer said very clearly to use at your own risk mate.

Did you let any of your cheated games end and therefore go into your theatre mode? I haven't been banned *yet* and I never let any of mine go to theatre mode, but we'll see, I could still get banned yet.
