Recently I've been playing more Spartan Ops Matchmaking, because the experience gain is so much better. However, I've run into a continuous stream of scumbags who shoot me in the back, plasma pistol or destroy my vehicle, and in one case - I shit you not - pinned me in a corner and humped me.
In the past when Bungie was at the reigns, they employed the "banhammer" to dispense justice on folks of a particularly jerkish nature. Is anything like this making a return for Halo 4? If someone is hardcore griefing me in Spartan Ops, what are my options?
