This convo highlights structural issues with Nostr.
Paying subscriptions for relays will never work. Subscription for social monetization does not work en masse. Same for clients. Ad-revenue does. Stick to what works and flow the ad-revenue from clients to relays.
Removing "spam and illegal content" defeats the entire point of Nostr. If gov bans free speech, and Nostr enforces it, then Nostr is rendered useless.
Nostr (or any decentralized network) needs a way of obscuring and anonymizing relays. So they can host whatever they want without gov sniffing them out. Illegal or not. Filters can apply at the client level. But remember, any filter risks censorship. Even good ones.
