When publishing to a relay, clients SHOULD ensure the user's `kind 10002` is also available on that relay. Relays SHOULD accept and serve `kind 10002` notes for any pubkey whose notes they store. Relays MAY scrape the network for missing `kind 10002` events. The goal here is that for any note served from a relay the user can also request the author's relay selections as a way of bootstrapping further context discovery. - -## Related articles -- [Outbox model](https://mikedilger.com/gossip-model/) -- [What is the Outbox Model?](https://habla.news/u/hodlbod@coracle.social/8YjqXm4SKY-TauwjOfLXS) +Clients SHOULD spread an author's `kind:10002` event to as many relays as viable, paying attention to relays that, at any moment, serve naturally as well-known public indexers for these relay lists (where most other clients and users are connecting to in order to publish and fetch those).
