Boosting?

Well, I know this didn't belong in the hacking section, so I figured I'd post it here. Everyone knows about boosting in Call of Duty right? Well, if I wanted to boost in combat arms, what would on do? I tried it by just getting kills on my friend but the whole "Abnormal gameplay detected" thing came up and didnt give me anything for it. So I was wondering how to do this for ranks.

Any help would be greatly appreciated.

You should kill him 10 times then let him kill you once, and keep on doing that. It usually doesn't give you abnormal gameplay
