Since there's no Moderator feedback thread that I can find.
Not only is he muting members he dislikes/disagrees with for extremely minor things, he's doing the exact things he claims to be muting them for.
Someone on the GM team sorely needs to reel this moderator back in, or preferably with his knack for just "moderating" solely based on people he personally likes and dislikes, just removing his privileges entirely.
