Endorsement Lists are the solution to #Nostr Web Of Trust issues.

User 1 endorses User 2, bringing them into the WoT.

Only endorsed users are allowed to bring new users inside the WoT.

Here's the kicker, it's hierarchical.

If a bad actor sneaks into the WoT and brings a bunch of bots, any person above them can knock the whole branch off.

Not sure if this could be added to NIP 51, or if it needs a new NIP.
