Still no can zap you bro. I do not remember including my nsec, unless it automatically does via NWC. As for an nsec leak, that means other, maybe bad actors, can spam or scam using your trusted npub which your #nostr fam trusts. The remedy that I know for that is suck it up and ditch your old npub after hearty warnings to the community that it has been compromised, and get a new npub toute suite, try to rebuild your follow list as best you can. Any other approaches I don’t know of?
