you mean 98% of the stuff on nostr is meaningless?
Where are you seeing that? I haven't seen any of those bot in a long time. All the people I follow are interesting and post good things.
I removed someone the free relays and the bots went away. The free relays are the problem and many people have the mentality that they want to keep nostr free. That's the biggest issue.
You just need to make nostr work with micro-transactions and it will stay clean. Require stats to follow someone, require stats to send DMs.
It's alot of work tho and devs are working for free so development of nostr is slow. It's fine. I like nostr at this moment. Reminds me of the early days with Facebook.
