In addition to Tony's objections to the bot, you have to realize that it's just posting random sentences in threads with real discussions going on. Some people (like me) read everything in flat mode, and all of a sudden here's a completely random post about whales and tahoes, and maybe that leads off on a completely unrelated topic and totally interrupts the thread that people are trying to read for content. Sure, threads go off subject, but usually it's gradual and people get back on track. I could just post to a thread with random sentences and it would be the same thing, whether it's a bot or not.

Plus, it's kinda dumb.
