And this is exactly the reason why. As mods, contrary to popular belief, we are not omniscient. lol Meaning that we will not always know when or where a bot topic comes up. The best thing that one can do when they come upon a bot is to simply report the topic. That will alert us as to where it is and deal with the situation.
Also, I think Cleod said he is looking into means to strengthen security to prevent bot accounts. However, as it is his senior year, and a hectic period for him presently, he won't be able to deal with it for a while.
