Ok I was surfing through the Garrysmod site and found this:
It contains obvious pictures from FPSB and a skin for every weapon from fpsb.
The Uploader says its HIS first Skinpack for all CSS weapons.
He doesn't give Credits to FPSB or one of the maker.
I don't how you think about it, but I think it's strange o0
How do you know that the releaser isn't from fpsb?
If he made the skin, he can release it everywhere he wants to. It doesn't mean he couldn't release it in garrysmod.org if he have released it here.
But there's always the possibility that he have stolen the skin from fpsb...
Forget that, I just took better look at the screenies
I'm not sure, but it's skinpack, so it's basically skins collected together so you can download them from one place.
