OK - maybe it's because I'm 72, and it sounds as if many of the posters here are young. Apologies.
Do you expect your stalkers to follow you if you move many states away? If not, then any move to anywhere of any significant distance will probably get your stalkers off your back. I don't see why it would be any different here than anywhere else though. And if you expect them to drop everything else in their own lives and move just so they can continue stalking you, you're probably clinically diagnosable as paranoid and I would encourage you to see a doctor.
Groups of people commit crimes - I can't imagine why you associate reporting a crime with mental illness.
However, a number of targets, myself included, have requested a mental health check before doing activism publicly, and have a clean bill of mental health. In my case, this was recommended by a lawyer, whom I had seen asking what I needed to know before doing activism.
We do see some people jumping to the conclusion that stalking can't possibly be done by more than one stalker, and if you report that, you are insane. But since crimes by groups happen everywhere, that reaction doesn't seem to have any valid reasoning behind it.
The U.S. Department of Justice reports that approximately one stalking complaint to police out of eight involves 3 or more stalkers.
