The problem with that is that we had a purple check sort of thing (and still do in some clients) that was based on Nip-05. It is sort of a verification of your name on a specific domain name but people give it too much weight thinking it means there is only one of a person with a check mark. So it’s ended up being confusing. I don’t have any really good ideas. It’s something I want to start experimenting with more soon.
Combination of persistency of the nip-05 (how long without change), your WOT follows indicator (more likely to be the real deal if many of your follows also follow for a long time) + some activity metrics (replies, likes, boosts ratios etc. for not spam —> depth/quality of content)? Similar to if somebody has been on Xitter or IG for over a decade with regular posting and following —> gives higher trust that it’s the real account.
I agree the purpose of the NIP-05 check was always a little confusing. We’d want ti start with: what problem are we solving? Impersonations is not a big problem for most plebs, but it’s a big one (or will become a big one if it’s not yet) for accounts with well developed brands. So some sort of method of social proofing that someone’s claimed brand is legit. https://i.nostr.build/3yev9G7HNGDzGW5z.jpg
