"Say a sat ๐ฅ a post/reply or something"... It's ๐ฏ technically ๐ฏ possible ๐ But also not possible until all clients ๐ show messages received from relays. For now, what I've implemented in Nosflare ๐ is it hashes ๐ every ๐ note sent to it. And this can be fine-tuned down ๐ to the hash of a ๐ฏ single word. So, for example, as I've ๐ค done ๐ with the wss://relay.nosflare.com relay it only allows ๐ค the same thing once. If someone else writes a note ๐ฏ that ๐ just says "GM" they'll be the only ones who can publish a ๐ note ๐ with ๐ just "GM" that day. ๐ฅ But as this is ๐ configurable, it can help at least stop spam that ๐ blasts the same thing ๐ over and over ๐ฅ again. ๐ Of course, it can be evaded ๐ค should they iterate those notes incrementally with something that makes ๐ค the content unique ๐ each time. In my ๐ mind, it's the best ๐ compromise ๐ for ๐ now, that doesn't ๐ฅ rely on WoT, ๐ and won't effectively ๐ฅ excommunicate interactions from new peeps on Nostr. note1cqve6sp235neaf7gwmsqw60u7r44793lnmsp9geh2yrslxs220jsy6r082
