i think the issue is not that the models on 3dbud are stolen (i hope not because i owned most of them). They used the WebDesign from
www.3drt.com which has changed now (both sites really looked identical).

The models are good quality with complete animation and import using Milkshape ASCII without any problem to MDL (except the Snake model).

Currently the Animation Frame Names are missing but it is possible to get them from their support.

The only thing to complain is they used multiple materials (about 6, left eye, right eye, body...) for the character models which complicates the use of shaders.

But over all you get great models which import without any problem (even the textures are in TGA and do not need to be converted) for a low rate.
