I need help with Black Ops 2

Ok so I know that I am new to MPGH and I know no one is going to want to jump on this. But the story is, I was a huge retard and thought Cheat Engine would work on Black ops 2. I am now perm banned from it. All i am asking is if there is a hack that will let me back into it, or any way just to play online again. I really was stupid. Also if i am banned from the servers, does it mean all COD servers? For say if i bought COD:Ghosts right now, would I be able to play online? Thank you and please reply!
