Every account has only the credibility that it can assign from other sources that can be evaluated unless the reputation build within the account is enough for the receiver.

E.g. if you post a proof of write-access from your established other social media, website etc.

No platform is trustworthy itself: garbage in, garbage out.

Nip-05 does not mean anything in itself. But it can show you have a write-access to your website etc.
