@AbbieNormal good point 😳
"you say you are the person posting at that social media account but i don't believe you" is never a problem i've ever had, nor expect to have
the converse would be more useful - if someone steals an account of mine or posts on some service claiming to be me, someone could challenge them to prove their identity via keyoxide
i like that it's an easy public interface to PGP, that gives people a mechanism to send me an encrypted message or verify that i signed a file without knowing much about PGP
not that those things are anything i've ever really needed before either 🤷
