question. #nostr what happens to your nsec once you delete your nostr account?? does it become invalidated, or can someone still regain access to the account by signing in again? ? #asknostr

There is no invalidating your nsec as far as I know. Deleting just removes it from whatever client you're using. You or someone could still recover it and use it.
That's up to the relay operator, but if you delete your nsec and no one else has a copy then no one can ever post under that account again. But public relays will inevitably delete old notes as space runs out.
