okay, so i want to mod mw2 using modio for online gameplay.... but will i get my xbox or gamertag banned? i heard IW doesnt care anymore because they really dont exist. but i just want to make sure, will i get banned for using modio to mod mw2 online? (yes i know, im playing mw2, but im already 15th prestige on black ops)
