This post states VAC doesn't ban for this however..
Their rules are contradictory and unclear, equalling an unsafe stamp of "VAC proof".
This is a post from a discussion on Steams forums summing up most of the talk in the thread but still not yeilding an answer:
"The disputes here result from an ambiguous contradiction in Valve's own VAC rules. These rules were not written by a lawyer - either care was not taken to clarify this point, or when Valve wrote these rules, they didn't anticipate that a sloppily ported game like MW2 (with no sv_pure setting) would VAC in the future.
By saying that Any third-party modification to a game designed to give one player an advantage over another is classified as a cheat or hack and will trigger a VAC ban Valve implies that a third party skin that gives a player an unfair advantage is bannable. However, they also state that Using custom skins, sounds or maps is absolutely not a bannable offence. This implies that you cannot be banned for any custom skin, sound, or map, as long as it doesn't modify core game executables or hook into memory, as defined earlier in the rules. This, of course, creates a contradiction in the rules when you have a third party skin that gives you an unfair advantage.
Despite this contradiction, since Valve specifically says that it can ban you for any reason whatsoever, and dictates what and what does not break the rules, I would not risk $60 and try to work around the rules by using this texture hack." -- coolbho3000, Steam forums.
So can you say it is VAC proof? I hear that sv_pure isn't enabled on servers and it's complicated to fix but they're trying to patch MW2 so skins will be rendere useless.

By the way, when I tested the skins a couple days ago I had no problems except for grass textures missing ( I only spotted it once outside the back of Estate's main house. ) Worked well for me, Thanks.
