Oh. @jb55 also told me that this is too many people and Nostr doesn't like contact lists this large. ¯\_(ツ)_/¯
Clients can send pubkey prefixes, so even if you have huge follows lists (to a degree) this can be mitigated
The query is only half the problem, note size limits is the other half. Also i thought we removed the prefix thing from the spec.
