## Expected behavior
When a user adds a pubkey to their NIP-51 mute list (kind 10000), content from that pubkey should be filtered from their feed, notifications, and anywhere else it would normally appear.
## Actual behavior
Muted accounts continue to appear in the user's feed despite being on their mute list.
