Welcome 🫂 

You will always know the people you follow because you store that on relays.

You will never really know your true follower count as this is based on client discovery across relays.

Here is a different view of your follower count:

If you look at some high count npubs like  nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s you will see they have a follower count ranging from 2K to 1M depending on client.

This is a feature, not a bug 😂
