Given what happened with Call of Duty: Modern Warfare 2 last year, Treyarch, the developer behind this year's Call of Duty: Black Ops, has decided to adopt a zero tolerance policy.
Speaking on the official Call of Duty forums, multiplayer director David Vonderhaar said "We are disinterested in making mini-celebrities out of douche-bags."
He went on to say "Given the opportunity I'd personally wield the ban hammer for anyone who thinks he is clever by abusing any glitches. Good thing I don't have the opportunity that often and we actually have a constructive, measured, and well-managed live ops team."
It looks like they're going to have their hands full.
