wss://relay.mostr.pub is special purpose as a bridge, so it is excluded.
wss://relay.poster.place was not included because although my gossip client knows about it, it has never had occasion to connect to it, so apparently of the people I follow and of the relay hints and naddrs I have encountered, none of them use that relay.
Trying to build a community here man poster is my relay
Well it does pass all the tests I just ran against it. looks like a solid relay.
Also, mostr relay is a regular relay just like ours. It runs stryfry which most people use. It just also sync to the fediverse.
