I have been searching for anything like this and haven't come across it. Nostr wouldn't work as well as torrents for spreading the files or as a centralized database for analysis and searching.

That said, I think there would be a lot of value in a project presenting the Epstein files on Nostr for better enabling collaborative discussion. There are a lot of websites popping up for analyzing the files with a graph data extraction. Discussion of the data analysis is even more fragmented across social media platforms and chat rooms.
