disagree. Anti-censorship You own your account data, not any client or relay. Even if all relays block you, you can still communicate with nsotr users through your own relay. If you are blocked by X, you cannot restore your account even if you are the president of the United States. Anti-censorship is to ensure users’ right to control their own accounts through protocol mechanisms.
It's only effective if your followers are on that relay. Otherwise, it's like talking to yourself with no one to listen. Correct me if I m wrong
Yes. Your contact needs to connect to the same relay as you. relay can also pull and store all relay data for broadcast like nostr.band. Even if you are not on a relay, you can communicate with your contacts.
