Sorry late reply, and no. Listen, MW2 is dead, on PC, that is. They recently released a patch but reverted back to the old patch for whatever reason. But other than that i've been doing these things for 6 months, haven't got banned once. MW2 IS DEAD, they no longer care for their game, unless you use a detected 'hack', you wont get banned.
@ScrewYouCookie me in your post if you want me to reply faster.
