It probably uses some kind of bot using computational linguistics. Our own weapons are used against us! On the other hand, the fact that it deleted the double trend trend from the first source (a typo) might indicate that the answer was compiled by hand, by a Mechanical Turk (Amazon), perhaps.
Note also that another answer from this user was deleted earlier, as it contained a spam link. Perhaps he uses answers like the above hoping to use reputation to make his spam less easy to identify?
