I'm pretty sure it used to. This is the saylor I've been following for a while.
I was following too but stopped because I have no way to validate it. I don't see an npub on hope.com anywhere.
All that really proves is that this is the same impersonator that it was before.
No, because it was verified at hope.com before.
All we can know is that it's not verified now. This indicates that hope.com has no idea about any nostr accounts. Anyone claiming to use hope.com is either an imposter or needs to contact their IT department. The fact that this account was never posted by saylor anywhere else suggests the former.
