I've seen some where I wasn't actually sure if it was machine or human generated. If human, it looked like a human wandered onto my blog (mostly my science blog, which I don't post in anymore), actually made a comment related to the topic at hand, and then linked to their blog with a tangentially related topic (such as religion or conspiracy theories). I honestly wasn't sure if some of these were robo-generated or human generated. In those cases I typically followed the link, and it was to some actual content and not 1 amazing trick to lose weight!, but not any content I actually cared about, so I ended up keeping the comment.
