Yesterday, I said that the "dark" part of the Fediverse was moving to Nostr.
This is because these folks don't like being "censored" and believe they are entitled to visibility.
They don't like moderation. That's what it comes down to.
They're fine with abuse and spam. In fact, they believe it's a net benefit to social media.
And when you look at Nostr now, that's what it pretty much is right now.
