The website mentions the network is pro-censorship:

> Pro-censorship: The protocol is ownerless, relays are not

> Nostr doesn't subscribe to political ideals of "free speech" — it simply recognizes that different people have different morals and preferences and each server, being privately owned, can follow their own criteria for rejecting content as they please and users are free to choose what to read and from where.

Nostr relays can censor however much they want. And users can just add other relays and route around it. That's fundamentally different from most other protocols, where user identity and posts are tied to a single server, and there is no means to just broadcast to another one.

On Lemmy for example you can't even find a post another server, since post ids are tied to a server. So despite post actually being cached on multiple servers, it provides absolutely nothing that helps with censorship or crash tolleranze.

From what I've gathered it's pro-censorship however since the user is entirely mobile and can change relays at will without friction that the power still remains with the user... the relay doesn't have much power in anything they can't keep their users from finding you, and they can't keep you from publishing elsewhere they can only choose to not accept your posts.

When I setup my account I list 3-4 relays that will host my content, if any one relay decides they dislike me and bans me no big deal everyone who follows me already knows to check 3-4 different servers for me and will find my content on the others, and I can update that list at any point in time just as quickly as I'm banned... so unless you can get every relay (which ideally are all individual groups with likely different rules / regulations) I publish to to ban me at the same time there is no real way to "censor" someone in the way we are used to currently.
