One can't predict your ban.
Maybe it's from only BO2, maybe it's from Xbox Live, maybe it's a temporary ban, maybe it's a permanent ban.
What is certain though, is that it can be (but not limited to) any of the above.
Yes you can get banned. Console or account. It also may just be a suspension but I doubt that. Modding warrants a ban, although theater mods usually result in account or just bo2 bans considering your console is not modified.
I feel that normal Gamers without modded consoles do you not know enough information about modding I feel for the infections you play custom game multiplayer or custom game zombies multiplayer or solo I have a hard time finding people getting banned but hey if you do not have a modded console and don't mod all the time sometimes you just can't help yourself you go online lol happy modding
