I've been meaning to do something about those troll comments because they were posted several years after the original threads and people are still getting confused by them. (Needless to say, Arrington wasn't Arrington.) There were 500+ comments all posted within an hour, obviously by script. They were dead not because they were voted down, but because we killed them years later. I thought that would be sufficient but it wasn't.
I have a hunch that was what prompted pg ("I never write a line of code unless I have to") to close old threads to new comments.
