Hey Vitor, are you sure you have your configuration correct? It seems your names object has '_' as the name, not your actual name.

It's correct. The spec allows "_" to avoid redundancy of names. In my case, to avoid vitor@vitorpamplona.com
so some clients will avoid name redundancy and some won’t?
Yep, client consistency is not a strength of nostr yet 😅
