(adsbygoogle = window.adsbygoogle || []).push({}); Is it possible to get a ban from part of Black Ops? I can't go into multiplayer but zombies works just fine :p

Banning is 100% possible, if you use some coding it can result in a insta-ban, but when you're banned usually zombies and multiplayer say " Servers are Unavaliable at this time". So probably the servers are just legitly down.
