Primal has a grey badge with a checkmark in it, to the right of users username. It doesn't make sense. What exactly does it mean? From my investigation it means the have a valid nip-05 address.

They copied X/Facebook. On X/Facebook it makes sense because it means you are verified to be a real person. Then on nostr it means you have a verified nip-05.

I don't think a grey checkmark beside everyone's profile who has a valid nip-05 address is necessary. It's not actually important enough to make users see that checkmark all the time in the feed.

Amethyst also has a purple circle with a purple checkmark in it but they don't force it because everyone's username although they do all the nip-05 full address under the username in the feed. Which I believe is unnecessary because they are long and why do I need to see their nip-05 address all the time? It belongs in their profile not the feed.
