Oh, ftr, I didn't wildly insert the nsec everywhere. There was no vault like Amber yet. I tried prly one client. Fwiw, it might as well be exfiltrared from Amethyst at one point. However, considering the amount of deliberate attacks, it could be the one stray client I checked. I don't know. It was years ago and the ecosystem wasn't mature.
Signing off now. It's just as easy to create a new account given all the overhead of abandoned npubs and old NIPs content.
