AoBot is good and it's free, it does like 100x more than kuk's bot. They are currently rewriting it. I haven't ran it in a while so I can't really say it's in tip top shape.
no bot is undetectable in the wardens eyes when its on it has a good chance to get you regardless. but anyways any game where you have to install via disks\download such as diablo\wow etc. are all very easy to catch bots\mh's etc.
