"Say a sat a post/reply or something"... It's technically possible 😏 But also not 👍 possible until all clients show messages received from relays. 😂 For now, what I've implemented 😂 in Nosflare is it hashes every note 😀 sent 😂 to 🎉 it. And this 🔥 can be 🔥 fine-tuned down to the hash of a 🌈 single 👍 word. So, 🎉 for example, as 🌈 I've done with the wss://relay.nosflare.com relay it only allows the same thing once. If someone else writes a note that just says "GM" they'll be 😂 the only 🔥 ones who can 😂 publish a note with just 🤔 "GM" that day. But as this is configurable, it can help at least 👍 stop spam 😂 that blasts the same thing over 🌈 and over again. Of course, it 😀 can be evaded should they iterate 🌈 those notes incrementally with something that makes the content 👍 unique each 💯 time. 💯 In my mind, it's the best compromise for 👍 now, that doesn't rely 😂 on WoT, 😀 and won't effectively 💯 excommunicate interactions from new peeps on 🔥 Nostr. note1cqve6sp235neaf7gwmsqw60u7r44793lnmsp9geh2yrslxs220jsy6r082
