Get a better global. Use nostr:npub1utx00neqgqln72j22kej3ux7803c2k986henvvha4thuwfkper4s7r50e8 algoo relay or theforest. Or something like nostr.wine or nostr.land, at least.

It doesn't matter, if they can't write to those relays because you can just have a default outbox to a public relay predefined in your client.
