Ok, that's .... a wild tool. So it copies your kind-3 to kind-30001 if you so choose and then lets you replace your list with other lists but you can also use it to backup your list to later restore it.

While that is great and lets me as a power user of nostr use other clients with more peace of mind after doing the backup, I was more thinking of a service that reaches out to those potentially noobs who screwed up - after all it's publicly available information. To track and archive who follows whom would allow much more than only offer to recover old follows. It would allow to detect trends in the network.

I wish I had the time and resources to throw an LLM at the problem. So much data to play with.
