Texture hacks are non bannable per Steam/VAC as it has been posted in a lot of other Texture Hack threads. Now IW didn't care in MW2 or MW3 but I have not heard or read anything for Ghosts. If I had to guess I am going to say they will not care since I have not heard about a secondary ban force other than Steam/VAC meaning you would have to abide by VAC's rules and regulations. Since VAC doesn't mind texture mods then it will probably be a non-bannable offense. I do not know enough about texture modding to say for sure though. And at this point this is all merely THEORY. Do not quote me on any of this after a texture mod is available.
