Simple tool to recover lost follows on Nostr.
Sometimes you lose a chunk of follows, due to mis-handling of clients. This tool tries to recover those follows.
It tries to connect to all relays from nostr.watch, fetches the kind 3 event of the specified pubkey and aggregates all follows. It also aggregates the relays mentioned and take into account which relays you have configured as writable.
You can also add your private key - do this at your own risk. If you do, it will sign the event and broadcast the new kind 3 event to all your writable relays that responded.
Edit the .env file and fill in your pubkey (hex or npub format), and optionally your private key (hex format).
If you don't fill in the private key, it'll write the constructed event to console and you have to find a way to sign and publish it.
Install dependencies:
npm install
and run:
node recovery.js
It takes about 40 seconds to run.
It will probably also restore follows from pubkeys you previously unfollowed.
This is not battletested. It worked for me, after I lost 75% of my follows.
One of the things I suspect caused my loss of follows was that one client 'forgot' about all the follows in the kind 3 event which didn't have a relay attached. I have not tracked down which client this is, I'm using a whole set of different Nostr clients and am unable to reproduce the issue.
