A lot of people have been getting instant bans from bo2 but there is a simple way to fix this. In order to mod bo2 with no ban you cannot use a modded or debugged eboot. Treyarch can detect the modded eboots and that results in an instant ban. This means you have to mod it using rtm with CCAPI and no modded eboots. I have been modding black ops 2 this way and I have had no bo2 bans or account bans.
