I looked through nostr.band and I can ser 2 “implementations” for NIP-50: page rank and spam filter
I was thinking on spam filter implementation but I dins straightforward solutions close to useless so I’m thinking about some complex methods instead for future
I thought to start with graphs first: saying that “if nobody follows author through X (3-7) handshakes then its a spam or something similar
Page rank is an interesting idea, will think about it
If interested, please see https://github.com/viktorvsk/saltivka/
Will be happy to answer any questions.
NIP-50 is not a top-10 priority for me right now but with some interest from others I would be glad to consider investing time into it
