Cutting/breaking model if re-uploaded into blender? (SL Copybot protection)

Hey all, I’m a mesh developer and I’ve heard of this method being used before, does anyone know how to do it?

Basically, once a creation is uploaded into SL, if it is then copybotted and re-imported into blender by someone else, the model appears broken/half missing etc, as a form of protection against copyright infringement, this disables anyone else from being able to use/re-sell the model.
