Rhen there is @cluborange that adds a simple upfront membership fee that selects only for people committed enough to pay and show up. This paid entry point keeps groups clean and focused on genuine participants who have already put skin in the game. It cuts out low effort automated noise before it ever reaches the conversation while real people connect locally for events and send direct tips without middlemen. Together with the NOSTR as the open protocol this layered approach creates overlapping protections neither could achieve alone. The decentralized base lets human networks grow globally with sovereign keys and instant payments. At the same time the membership filter provides proven economic selection at the community level. Real events and focused discussions happen naturally among verified members and multiple such paid communities can run on the same foundation without relying on one central gatekeeper.
