To anyone who does this glitch, be prepared to be reported a TON. The stats are legit, but you will still get reported. Most likely nothing will happen, but if it does, just know that there are assholes out there. Also, try not to do it for too many of your friends and play with them all at once. It looks VERY sketchy, and it will definitely attract ALOT of attention. Just thought I'd let everyone know.
The stats are legit, so why would you get reported? You only would if you're a dick & piss people off. I went up to 8th prestige level 47 with 17,000+ kills & have been playing with it with a while now. Nothing has happened & no one has reported me. I just got called a no-life by angry squeakers.
