Thanks! I tool a brief look at the Nostr code and believe basically all of my ideas are applicable and can be implemented without any changes to the Nostr protocol. Could even be done using a proof-of-concept “peercuration”-relay. nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg could for instance do it.
