This is why we need burn notices as a NIP. A formalized way to announce, and to like, “burn notices” which, with the help of the network, can identify the new, secure replacement npub.

New or existing event kind could be used but a “hint” to the new npub could be defined. But it MUST be signed by the burnt nsec, imho. Think about it.

Thresholds for likes/zaps/??? by not-new/friendly npubs could help resolve conflicting burn notices when they occur.

This could add value to each person’s network.
