It didn't surprise me that you were gaining that advantage over other players like you did and was also banned for the same thing before. I really could feel the difference between fighting you and other players at the same time. I had given you a chance earlier to play clean even though you were evading your ban a numerous times, now no chances will be given from my side. Wait for a final decision by a manager.
on edit : the reason given might be a little confusing, but it should be "weapon behavior modifications".
