Because they're incredibly inaccurate without adding a centralized mechanism.
To calculate my followers, you have to look at every single npub across every single relay and look at their contact list to see if they follow me. That isn't very efficient.
My favorite analogy is counting your followers on nostr is like counting how many people have your cell phone number saved in their phone. You can’t.
Someone should vibecode a solution that gives a more definitive usercount.
A specific type of relay would be enough to later aggregate this data, isn't it?
