Im 10th 70 on mw2 and i really want to be 9th 70.

I therefore want to derank myself.

I am fully aware that the only way to do this is system link.

I refuse to give anyone my details as i have been hacked before.

So can someone, that knows how to do it, tell me how to do it then i can do it myself without giving out my details.

Thanks for your time guys.
