I see...

nostr.band is not actionable... just a picture.

At least nostr.watch has an API, but there's no users/events count apparently.

I don't see those resources to be really useful unfortunately.

Any knowledge of some actual source of data?

eden.nostr.land is one i subscribe to as well... yeah it's massive, nearly at the top of the list

note that relay.damus.io is constantly being wiped
