What char or acct is affected when banned?

[Mag]

Hi. I am hoping someone here can clarify how a ban works exactly. I'll provide my scenario and any help would be greatly appreciate. I have multiple cd-keys, but with my main cd-key (the one I got from my retail box), I make all my characters. I never play Diablo 2 with that cd-key, I always use the loaders with the other cd-keys, and run my bot with all the other cd-keys. So, If I were to ever get caught w/ mh and get banned, would they ban the cd-key that's currently being used and all the account made from that cd-key only? or would they ban the character itself? I ask this cuz I'm playing my main char on a loader that is on a separate cd-key, thinking that if I ever get caught w/ anything, they would just ban that cd-key and not my char.

any help would be greatly appreciated.
