The 2 cents of a noob...
Coming from other modding communities (HalfLife, Unreal, etc), I can honestly say that having the product of your hard work, blood, sweat and tears stolen and used for someone else's profit without so much as a nod of thanks in the credits is not only insulting, it's a hell of an incentive to find a new hobby.
I just got STARTED on this game, so I want the mod community to stay alive. Stuff like this is how mod communities die...
