Although we'll soon pepper each other with bullets and trade drone-guided explosions in Black Ops 2's multiplayer later this evening, Treyarch still wants the chaos guided by a set of rules keeping abuse in check and ensuring friendly times all around. Eurogamer scoped into Treyarch's weekend post of its stiff-sounding security and enforcement policy , and among standard ban pitfalls surrounding piracy and hacking, players using the in-game live-streaming service with "unlicensed content" such as music risk a ban as well.
Treyarch's policies also hound boosters—players "colluding with another user to exploit the game for the purpose of gaining XP, prestige, game score, weapon level, or in-game unlock"—with equal fervor as hackers and glitch exploiters. In most cases, culprits receive temporary bans with increasing severity per case until suffering the almighty permanent ban which locks out online play, permanently blocks leaderboard appearances, and resets stats & emblems. It's sort of akin to a drumming out ceremony, except with less ripped shirts.
Treyarch's post has more details on the no-nos, so head over to Black Ops 2's forums if you want a look.
