This is different because it bifurcates the network. End users will have to understand which Lemmy providers federate with whichever others in a way they don't have to with email today. It also feels like the bar to classifying these two providers as malicious is a lot lower than with email.

This feels like a bad idea. Let's look at some popular federated networks:

1. Anyone with a phone number can call anyone else with a phone number.
2. Anyone with an email can email anyone else with an email.
3. Anyone can setup a Matrix server and message anyone else with federation turned on.
4. There is one DNS system despite it being decentralised.

This feels like a modern day IRC netsplit and we will all lose. This decision needs to be reversed once better tooling / organisation is put in place. Blocking should be done at a different layer (e.g. call blocking or email spam filtering).
