Edit: I think people are missing the point. I don't particularly disagree with any of the replies. HN's commentary is pretty superb in part due to censorship and I agree that without a big stick being used open communities turn to trash. My question is though, why are people defending the mods here but when FB tries to do the same thing, we act like FB is some cyber Gestapo out to dominate speech on the web. It boils down to HN good, FB bad; it's shallow and hypocritical. And I maintain that shadowbanning is an abusive practice. If a user's behavior is such that the user can no longer participate, the user ought to know this. Shadowbanning is like internet gaslamping. You are telling the user one thing while the reality of the situation is different. Websites should not be playing these mind games with their users.
