After we announced that we'd be starting to require registration on the site to comment, many in the community immediately accused us of censorship. Our policy always was and continues to be that our moderators remove posts that are obscene, threatening, libelous, or defamatory, and those that contain personal attacks, personal information, and racism. That means you can criticize anyone in civil government you want, but you have to do it without using the f-word (no matter how creatively spelled).
Your biting criticism has a much better chance of improving things if it's substantive and not pointless name-calling anyway.
The fact that you now have to register is not censorship, everyone can still post all the same stuff. Only now the Register is going to have some idea of who you are -- but just the Register. We guard the identities and personal information of our online users with every shield available to us. So the venal public official you justly or unjustly criticize is never going to know who you are.
From a censorship standpoint, registration has no effect at all.
