Thats pretty cool, so the concept is a new relay is unaware of old notes and this tool pulls them and essentially rebroadcasts them to the net new relay? 😎🤙
I set up the #Nostr relay on nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct to backup my notes and other stuff. Then I used this tool to backup all my old events.

A nice side effect is that all of my old posts show up instantly in Amethyst, rather than being limited to more recent stuff
