I wouldnt recommend to follow everyone of a users follows. Your follows should be fine tuned by your own to get the best signal for you. This is also why I avoid global like the plague. For me its all about building a follow list of my own and discovery within the wider network.

The purpose of my curated follow lists are so that people who connect to me can scan it, follow people they didn't know had a nostr account, lift up visibility of people and bringing them together, organically. A social thing.
