I think the underscore handle in “_@orangepill.dev” is currently being treated as a @name of the NIP05 identifier by clients. I mean you could have a username as @bobross in your profile and a NIP identifier as _@orangepill.dev but that “_” is treated as a NIP05 name in the Nostr.json file.

So I added that to my Nostr.json and created a new pubkey/user to test. See this user:

I added “_”: “hexpubkey”
