Treyarch has published its Call of Duty: Black Ops 2 security and enforcement policy, outlining the behaviour that will result in a ban.
There are plenty of obvious offenses in there, for modding/hacking, for example, and for running pirated content. You'll also want to avoid using modded controllers, IP flooders and lag switches.
Boosting is a big no-no. Boosting, for years a problem with online games, involves colluding with another player to exploit the game to gain experience points and unlocks. Glitching, or abusing an exploit in game code, will get you banned too. This might include using a hole in the map geography to intentionally go outside its boundary.
You'll face a ban for using offensive behaviour, such as aggressive or racially charged language. If you create an offensive emblem, that is, one with sexually gratuitous images or racist material, you could get a ban.
New for Black Ops 2 is an in-game live streaming function that outputs to YouTube. This carries its own ban conditions. So, don't pump out offensive live streams or stream unauthorised content.
Offensive content includes but is not limited to foul language, racially charged language and nudity," Treyarch said. "Unauthorised content includes but is not limited to unlicensed music, TV shows, movies and brand logos.
Black Ops 2 launches at midnight tonight and is expected to set records for game sales and online play.
