A red warning letting me know that this could be an imposter would be 🤌 Not sure that would help if the Imposter gets to Nostr first though. I can imagine the actual person getting flagged in some cases. And the flag would technically be correct if you already follow the imposter. Somewhat complex issue

Not a silver bullet, its true.
An honest person with a common handle WILL be flagged for attention. That's okay.
Not worried about cases where the scammer is here first - scammers want to steal credibility from existing accounts, this breaks their business model if they have to build followings the hard way
True. Definitely an edge case.
I saw some npub claiming to be Linus Torvalds the other day.
My proposal won't fix that.
NIP-05 is supposed to, but its easily gamed since the DNS system has perverse incentives.
Yeah, DNS was my first thought but that has scammers too. And then recently there was a story about some domains being easily taken. There's no perfect system, but I think certain people swapping npubs IRL also helps. Especially bigger names in a particular circle.
I think the actual answer will be an imperfect combination of multiple approaches that reduce risk down to very small levels for most people.
