Honestly, I don't understand the problem. Either you are talking to a bot and then you realise but there is no harm done, or you recognize a bot and get annoyed but then block them and continue with your day, or you interact with a bot and it starts asking for personal details or tries to get you onto another platform like a telegram channel, or it asks for your seed phrase... Things you should not give to a bot OR another person.

So honestly, I'd like to hear real stories about what people are experiencing so we can catalog it and understand what the problem is.

Saying "how can we identify bots" is like saying "how can we identify nostr users who have blue eyes?" Like 1. You can't, 2. Why do you want to filter them anyway?

If we treat bots and people the same, then the question becomes: how can I protect myself from scammers (which I THINK is the real question)... That's an answerable question but still difficult to answer until we have case studies.
