Yap, see that happens. I have seen one where one guy stays 50 feet in the air and every shot of his explodes. Also another one where a guy is invincible, he owns in Domination for sure. Also I have seen unlimited noobtubes. Crazy stuff.
I actually play more Bad company 2 for real war experience but I do enjoy MW2 for the different experience. I still have black ops unopened as I am not too interest in it. I am impatient for MW3.
After been hacked, I will have doubts putting any photos in my PS3 as you never know when another will hack your account. I thought this only can happen to PC but I guessed people can do it in consoles as well.
Also it really kills the fun in MW2 when you are dominating with 65 kills and 0 deaths. I did not mind being noobtubed but when you don't even have a chance to move, that is stupid.
