I get your concern about multiple relays sharing block lists - not sure if it’s really preventable but I understand. Are you not doing any IP rate limiting on nos.lol? Only pubkey/content/report based? I know you request PoW from some new pubkeys too? Do they ever provide it? Curious how much spam you’re seeing etc

on nos.lol no IP rate limiting. only rate limiting for pubk. but if fresh pubkeys are too many coming from an IP, IP gets banned. reports are only checked on nostr.mom. there are wikifreedia pages for those if anyone is interested in what is going on in the relays. i don't know if pow is provisioned at all. i don't read logs 99% of the time. i doubt anyone put the effort to provide pow. but if pow was popular it could be overriding many algorithms for sure. i could allow many notes if they came with pow. i didn't see many "replyguy on nos.lol" kind of notes. my relays probably handled it fine. i don't even count spams. i am very lazy compared to you 🤭

Always appreciate you, thanks for the answers. Seems like you have a pretty good solution going at least. So temp IP blocks only when many fresh pubkeys coming from one address. Could still cause issues for VPN users as you pointed out but at least better targeted. Our problem is we don’t have any IP/network info on our aggregator so we have to make decisions based on only the events. I think the new system will work though.
