I don’t know enough to know whether I trust it. I’ve used a good number of nostr apps and any could be compromised, right (like primal, damus, etc)? I’ve used my nsec on iOS and on desktop.

Part of why I love nostr is that it seems easy to restart from 0 as long as you can rebuild your follow list. As far as regaining your followers, I’m sure some web of trust implementation will assist people in knowing when someone’s nsec is compromised so they can find the new account to follow
