>>They'll do whatever let's them keep operating.

But that's the point - western authorities can't do anything to shut them down and Chinese ones don't care either. Sending a list of buyers is effort and takes time....so why bother?

I mean obviously we're just speculating, I just mean that a random Chinese website would have no reason to respond to such a request from say an American authority(and it's probably unlikely that anyone would ask, seeing as in a lot of places just owning such a device is not illegal, using it is)
