nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 I imagined that if my nsec is compromised I would set up an automated post on this account. Something to the effect of:

This account is compromised, please unfollow it and follow 'new npub'

I could choose the interval in which it is posted. Once an hour or once every 5 minutes. Users who are still active will migrate to the new npub. Dead accounts will not.
