watsup guys, im considering whether or not to just buy a j-tagged xbox and a modding account, because im sick of this whole GPD bullshit. But i know verry little about J-tagging with blackops... I know what j-tagging is but could somebody give me a quick rundown of what exactly it can be used for (pertaining to Blackops )???

and if i use it for more personal use and not start selling commercial lobbies etc, is it likely i will be banned. Because what i'd like to use it for is to get me to like 7th prestige, maybe run some small mods like class mods or maybe 4 perks or something if possible. If anybody can just fill me in a lil it would be appreciated!

THANKS

MERRY X-MAS[b]

EDIT: and do we still need keyvaults or is there something diff? and do KVs cost money? or is KV a thing of the past...?
