I contacted xbox chat and reported this and they advised me to "Is post that link onto the forums for the enforcement team to see and to report this issue."
http://blackops2modbox.com/ is one of the sites I have seen so far, there is possibly others also
Just to make You aware of this Hack for the game Black Ops 2
Apparently it lets people know where You are in game (wall hack) prestige level hack and anti ban etc etc
It is realy frustrating playing against players that use this hack/software to get the upper hand...
I do not mind losing or getting killed, as long as the playing field is level
Please sort this out so that the game becomes enjoyable again, not just for the hackers that are no good at the game, but for everyone that play's it
