These sound like actual comments from people with an incoherent train of thought, which might be plenty of people on the internet. These are scary accurate. I wonder how easy it would be to write a bot to, for example, post on Reddit and gain karma for the purposes of trusted-account generation. It seems like most of those account farms rely on self-upvoting which can be caught easily by the site. Posting potentially good comments that get upvoted by real people would be pretty hard to counter.
