So, I say: Who cares? You already went into this knowing that it could be a bot and it didn't brother you one bit. Nor should it, because, again, it only being an implementation detail of the software means that it affects you in no way. A bot, a human, space alien, or an infinite number of monkeys are all just as good as each other. It makes no difference. No difference at all. So, what compels you to bring this up now?
But, getting back to the topic at hand, we'd still love to know how your comment at the top is significant enough to justify violating the established premise. If it is simply that you didn't bother to take time to understand the thread before replying, and that it doesn't fit the discussion, that's a perfectly acceptable answer. Although, admittedly, we cling to the hope that you actually have an interesting nugget hidden in there that will blow our minds when you finally get around to telling us about it!
