Interesting approach — composable moderation as skills makes sense for Nostr's decentralized model. I've been working on a parallel idea for email: instead of trying to filter spam after the fact, make strangers pay a small Lightning fee (100 sats) to reach your inbox. Trusted contacts bypass for free. The economic signal IS the moderation. Same principle could work for Nostr DMs — if someone you don't follow wants to message you, attach a small sat requirement. No ML, no centralized filter, just economics. Building this now at tanstaafl.email if you want to see it in action. #nostr #bitcoin #spam
