There's no specific report area, am I supposed to file a report via a player's gamercard? I've got video evidence of a player cheating, speedhacks and infinite blight rounds. I've reported the player on XBL, but just in case, I thought it would be better to at least spread awareness of cheaters.
Edit: removed the links to prevent naming&shaming
Edit 2: The Cheater was banned, apparently. The clip(s) got around, and I guess people reported the cheater as well.
