I remember the Hello Nostr thing that people were talking about but I didn't happen to see any. But it also might have been a very busy week for me offline.

I was hoping to subscribe to a service like you might do with a pihole that blocks ads, or an email provider that blocks spam. One that maintains a good reputation for being limited in their scope, who doesn't block political content they disagree with.  Should such a service arise and suggest a protocol, I'll plug gossip into it.

I have several things in mind that you might like, will get back to you when I launch the next one :) 

 you have notes that are moderation actions and you subscribe to them, and you can subscribe to pools of these from many users
