They might blackmail you to get at their higher level targets. Still not much you can do about it, unless you work at AT&T or Verizon or Lumen, or you report the blackmail to the FBI, something most people probably would be extremely uncomfortable doing given our security services tend to suspect anyone who reports anything to them as the first prime suspect. Maybe there is a statistical reason for that, but it also deters any cooperation. And going through channels often is blocked by business/profit concerns. Espionage probably often happens through relatives and friends of VIP's, though that's a guess.
