For the last week we've been having a problem with a troll who shows up in the small hours of the morning every night and leaves incoherent but highly offensive comments which for some reason the spam filter doesn't catch. I imagine that a week or two of comment moderation should cause this troubled soul to get tired of his game, so while I've never been a fan of comment moderation I'm going to turn it on for a while until we shake our troll. Be assured that all comments that aren't obvious trolling will be approved as soon as we see them.
Sorry for the inconvenience.
