I think about the fact that I cant get my twitter account back and never lost a password to it. I imagine if I were important, or my income was based on social media monetization that the impact could be devastating.
At least with Nostr I can have some attestation that doesnt exist with centralized services. From a lost/compromised key with a reputation built to new one, Id rely in large part on updating the NIP05 from domain I control to reference new pubkey, and list of people i follow to help spread that update.
But we're lacking a standard to do this. Even when NVK accidentally deleted his account it wasnt all that easy to sort through that. Without it being dead simple we can count on most users giving up with nobody to call/email before they sort out what to do on their own.
