Another website that steals our products

This website if not taken action upon is going to make a lot of money out of things they never even created/made/did and probably don't even have in stock or for download. But on the other hand, you report them, they get shut down, they just open a new website or the same site under a new name.

Are those really 3D models? Couldn't that be just a "fake store", where they display just the images and don't actually send the model? A bunch of my models are there, but... how?!
