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.
