Is it done by majority vote or does one instance have more control than others cough cough lemmy world cough if so then this is not really federated is it and with each instance we now have basically upgraded mod power to admin power so one more question is each instance independently monetized?
By default, all Lemmy servers can talk to each other. An admin for a server can choose for their server to not communicate with any other server.
That means that people on those two servers can’t communicate, but makes no difference to people not on those two servers.
That’s it
