Have you tried to comment in reply to @joe.public? When you do, you will find that your comment is invisible to you. The #irredeemables list doesn't just completely hide all @joe.public's comments and posts - which is why you don't see censorship - it hides your own comments from even you when made in reply to @joe.public.

For too long we have been censored and not noticed it. It's time Hive took control of it's speech from those that would make themselves the publishers of our words, determining who can speak, to whom, and what we are allowed to say.

This should not be done in darkness, but in the bright glare of our close attention.
