in my relay #orly there is a spider that, based on the first and second degree follows of the designated owner npubs can fetch all the events of first and/or second degree, and it can either just grab the stuff that helps you find people (relay lists, profiles, follows/mutes) or it can just scrape for them. i didn't make it automatically use the relay lists it has in the db to keep it simple but it would be simple to add that.

if you paid for one relay, and every 10 minutes it was fetching events from everywhere, a) it would be worth paying for and b) everyone would find everything.

but it requires auth to really work.
