I've known about so-called "bots" on the MSN (now Windows Live) instant messaging network since, well, I signed up. I recently (several weeks ago, actually) set up a hack to Google Talk that would allow me to use that program with the AIM, MSN, and Yahoo! networks. Which means I can talk to the bots again. And that means they can see me. One in particular, called "Spleak" (no link for you, ad-pushers!) is supposedly a virtual person that you can talk to. I have one word that can describe it: unsophisticated. Say anything more complex than a sentence fragment and you lose the bot's comprehension, causing it to reply something along the lines of, "I don't quite understand you."
That's all right, since there are plenty of (menu-based, harrumph) features to enjoy, and the polls are fun (except the "Hot or not?" questions, which are kind of pointless, since I don't know who any of the people are usually). But when the program starts firing random ads at you, when you're marked as busy in Google Talk (I don't actually know what I show up as on MSN or AIM), it gets annoying. Just saying. Hope none of you ever get hit by bots like this.
Fortunately, "Spleak" is the only bot that ever does this, so it's not widespread. But obviously it's possible, and other makers might integrate this functionality into their bots. It wouldn't be so annoying if those irritating programs could understand and communicate with you when you explode after they send an unsolicited message. Their "What?" responses just serve to make you angrier...
