They both look something like what a markov generator would put out if the generator was fed text from the parent nodes. This seems to a be a common spammer technique these days.

The second one, though, looks like there might be a human behind it. The usage of '-MTd' as a cmd param doesn't appear in the parent posts, though the DOS-style '/MTd' does. It would likely take a sophisticated natural language generator to be able to come up with that.

As a side note, I believe it was tye who hypothesized that the first strong-AI will come out of the escalation between spammers and anti-spammers.
