Day 3 on Nostr, now wrapping my head around relays. + super excited about Amethyst, Amber and Citrine, though still trying to figure out how to get everything running smoothly. 😂 Huge shoutout to @greenart7c3 for the great work

Thank you for the detailed explanation! Being new to Nostr, I'm still trying to fully understand the relay concept and its possible implications: 1. What prevents esp. large relays from/selling relayed data to the highest bidder (data brokers, marketing/profiling companies etc.), and/ or hand over to a government agency if requested? Does it make a difference if a relay service is a paid service or free privately managed one? 2. Relayed data is all unencrypted Json, right?Ist it stored permanently on relays (like all BTC Txs/UTXOs on all participating nodes)?
