I see - though I wonder how much longer that will be possible. I expect the spam problem will get a lot worse at some point. When there's like 10000 spam posts for every real human it will be a defacto arms race between spam-generating AI and spam-detecting AI. Fortunately we can use PoW notes to tilt the balance in favor of the defenders. We're lucky to be part of early nostr where it's still niche enough that we can find each other!
