so using relays in very specific ways is not needed and against what i fell is core #nostr thinking, you can of course do it that way and people will but that is #fedi thinking and no surprise nostr:npub108pv4cg5ag52nq082kd5leu9ffrn2gdg6g4xdwatn73y36uzplmq9uyev6 is that way inclined or nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn
you can handle #spam and isolate a feed quite easy with #filters , i mean for a #japan feed you just need to look for the chars
given even in japan nostr is going to grow huge you will end up needing the same tools we are all using so it would be wise you stay with the main lines of dev so we can amplify our efforts while we are still small
thanks for the link btw
geofilters are lame as well, not hard to bypass either
