In their github they specify that they expect the snitch lists it fabricates to be used by relays too. Much less obvious than clients.

My issue with this is not just that it's censorship and that it causes ME to have to spend resources and time avoiding it by finding uncensored clients and relays. The long-ranging problem is that it turns relays and clients into editorializing platforms, which opens the door to regulation and prosecution. It's basically either Nostr becoming Facebook/Google, or being shut down and people running relays and writing apps getting sent to jail.
