My GPG key on public key servers is identified as AA4DB1FB.
If there isn’t a trust pathway from keys you trust to keys they trust to keys… and so on to me, you could go by the following celebrities with well known domain names (you’ll find them linked from many, many websites) and keys and/or ids/fingerprints served on those personal websites by https.
Not recommended if you have a high stakes reason to send me a GPG encrypted message. In terms of signature paths, I am not closely connected.
You should definitely not sign my key on this basis.
I link to a trust path website to illustrate, to actually verify for yourself you would need to import the relevant keys to your gpg client.
The connections to me come via Skullspace members.
