Your models are suspended because you triggered suspension mechanism by using certain word for tag. Let's put it this way: CGT doesn't like weapons and especially doesn't allow selling models of weapons that can be 3d printed, because of that every single 3d model of any kind a weapon must go through the administration so that it can be checked, checked what it is, what is the main usage, can it be modified to 3d printable model or is it already 3d printable.
