I saw a guy named M.Piccolo on the ESForces.com west #3. It was a team game, and team damage was off. This guy was apparently on my team (green reticle), but he was killing me. When I confronted him about it, he said he was using some exploit to get on the spectator team but be in the game. Apparently he was killing people on both sides, but because of the green reticle, no one could target him with melee. As if that wasn't bad enough, he basically had the run of the places because he could kill anyone he wanted, and anyone who ran across him thought he was a teammate.
