That's not the point. Multiple sources in ban report section claim that their bots were teleported to a place where they got stuck by a GM before the ban. A human would freak out and hearth out, while HB-fueled bots would hump the thing they got stuck in, then do the dance, thus revealing themselves completely.
Right now, Blizzard has a quite efficient way of detecting us. I do believe that there is no hard detection, but nonetheless, something is going on. Unstuck routine is a threat, and big freaking time threat.
Although quite honestly, I doubt that your devs will address this any time soon. It's been two months since ban rates have skyrocketed, and all I see from your lot is "nothing is out of order, move along".
