One of my friends said he was playing HC KC and got a load abuse from a player. A few days later he's playing HC KC confirmed again and somebody gets a MOAB. So he checks the scoreboard and it's the same player who gave him abuse who's got the MOAB. He's got 30 kills and somebody on the other team has 30 deaths. Sounds a bit suspicious eh? So he checks the theatre and sure enough the guy has been boosting with the tac insert.
He then sends a theatre video showing them boosting to IW and the 2 players in that video have both had all their stats reset for this game! Oh,and a 48 hour ban.
