As best I can tell no one has any liability with respect to what's posted except the poster.

So there's absolutely no excuse for third-party censorship. My understanding is that nostr was created to be censorship resistant.

I think the next big step for nostr is clients and relays that don't try to censor content or speech.

This is like the early days of the internet when groups like AOL and Prodigy tried to create walled gardens and cages. To allegedly protect YOU! from the real internet..😆
