We need some way to bot-proof some content, like WoT-key sharing. A "send to npub[]" feature, where npub[] is a WoT-based list. Send a key for their keyrings for content open-able by that list only. Rotate keys weekly or monthly to keep leaks from ruining it. That can be handled in the client background process.

Some content only your WoT network will be able to see.

You could also send bot-bait to oust them with the inverse, content your list knows to ignore by an encrypted datum.
