My friend bought a 30-70 power level (idiot) and the character was level very quickly~
So I decided, Heck, Why not see what they do to level. So I went and observed the character and it was (bot movement too) just running in circles killing mobs- A profile I know of for glider (in tanaris). By the way- he got a 3 day ban at lvl 64 and when he got it back it was lvl 61 again.
