Enjoyed this conversation. A lot of it was way over my head, but I seem to like to torture myself that way.
So, with Pubkey, a user would be signing up through a homeserver, and if that homeserver decided to censor them, they would be SOL and have to start over, just like with Mastodon? Am I understanding that correctly? No posting a note to a few different relays for the sake of censorship resistance via redundancy?
