The Mungol example is unrelated, and was flawed to begin with. The video our not-totally-hacking friend here refers to showed Ykky, member of our faction, buried about knee deep in the ground while attacking them, apparently "hacking." As anyone who played during that time knew, it was very common client-side graphical bug that didn't affect anything whatsoever, rendering the case quite so obvious. Besides, who would use a hack that causes you to walk bit inside the ground to begin with?
