Tweet text: "One of the cool things about Nostr ("Notes and other stuff transmitted by relays", a new decentralized protocol that replaces things like Twitter and Instagram)—beyond censorship resistance—is that you aren't limited to 280 characters."
Sounds like Usenet. What will it do about spam?
It seems that would depend on, or change according to, each individual relay.
>If spam is a concern for a relay, it can require payment for publication or some other form of authentication, such as an email address or phone, and associate these internally with a pubkey that then gets to publish to that relay — or other anti-spam techniques, like hashcash or captchas. If a relay is being used as a spam vector, it can easily be unlisted by clients, which can continue to fetch updates from other relays.[0]
