with RAF you can get 1-60 in 1~5mins, no exploit.
i remember there this system that if your friend got a level 80,
your friend can ding you to level40 , 2:1 ratio
but that system only allow you to reach lvl60, the rest you have to grind.
i remember seeing this in org between bank and AH, a player keep dinging till 60,
the only problem is the gear and the rep stay the same, so you still have to grind them
if you have 2 friends(NOT 2 level80 toons) then that easily cap 60

or maybe like perunding said^

go check greedygoblin.blogspot there teach some way to con-i mean to earn "honest" money.
like buy the engineering 1stack(1,000) of epic bullet,
but sell back only 1(one) bullet at the 70~80% of the 1 stack(1,000) market price,
the huntard will buy it.
if you feel pity the huntard, just sell 100 bullet for the price of 70~80% of 1 stack(1,000) epic bullet market price.

others will just complain why you cut market price to 70%

i have seen people buy 1 glass of milk for 5g~14g, its an amazing world... or warcraft.
