I said that way back when I first started using Nostr last February. Include a zap as part of posting a reply. Relays don't accept notes that tag another user or note without a zap. Users can set the threshold for being tagged or replied to as part of their profile data. Could be 2 sats or 2000 sats. Up to each user. Put a value on joining the conversation.

Makes sense in ky opinion
Any idea why recently there have been an increase in the number of bots? What could be causing it?
Someone or some group. There's a handful of bots at once which leads me to believe it's an individual rather than a large group
