How great of you to ban him, announcing the decision publicly without letting him answer to it. He's one of the few members I feel I can engage with in a debate without having my arguments being totally misrepresented, and while I don't always agree with him, his elaborate perspective is valuable in threads that would only otherwise only end up being a lot of back-patting or polarized flamewars.
What exactly did you ban him for?
"So no polls on how we can make the site better or change the moderation. No more, "Let me explain my feelings on how I mod" discousions."
It seems he had critisized the moderation and/or certain moderators...
