nostr is too much like x, full of spam and the devs haven’t solved the issue yet, they keep trying but failing. The Facebook system is better where you need to send a follow/friend request,

it should cost sats to follow/unfollow someone that will reduce spam, and nostr needs private profile to reduce spam even more. I am confident that’s the direction eventually nostr will go

Build it, then.

You talk as if this was the only solution, imposed upon everybody by the Nostr overlords, but it is just one guy doing a thing in his client or in his relay, while other people can do other things. Nothing is imposed, everything is optional and people can pick and choose the solutions they prefer.
