Plutonium

interesting, cant say i remember using any cheats while playing on any plutonium clients, could modded servers be the culprit?

I had gone to get on Plutonium today to play some black ops 2 zombies, and it needed me to log in. I thought it was weird, but I had been having some weird internet problems so I thought it could be that. when I entered my login info an error popped up saying I was banned. The ban is only for 4 or 5 days so I can wait it out, but I would like to know what happened to ban my account so I can continue playing classic cod's safely.
