They can't shut down the service because there is no single service. They can go after individual servers, and that is fine. The admin is responsible for what happens on their server.

Why would an admin run a server if they might have the feds knocking at their door? Sure, people might run nodes that host only their content, but they sure are disincentivized from running any sort of shared service.

This is the same problem as TOR exit nodes and why 3 letter agencies run most of them.

		This is the same problem as why an admin would run a forum if the feds might knock at the door, or why an admin would run a website about cats if the feds might knock at the door. It's an overblown fear.

		Maybe the live where the feds can't get them?
