"At the time of the alleged offences an offline purchase would cost the purchaser about £2.70 for the same number of gold pieces as would be generated by a £6 bond purchased from Jagex," the court adds. It also amusingly notes that "the number of gold pieces generated by a bond might take some 15 hours to earn by completing in-game tasks." Get grinding, gamers.

That "15 hours" number seems misleading, I highly doubt a fresh account can make enough money on it's own in 15 hours to buy a bond (that gives it ~14 days of membership status). I'm no expert at Old School Runescape, but I've tried my hand at some moneymaking and most decent methods require a prior investment of many hours just to make them accessible. I wouldn't be surprised if the average bond grinder has been playing for so many hours that the amortized cost of a bond indeed works out to be around 15 hours of game-play time - though this still only works out as long as at least some people are purchasing bonds from Jagex and then selling them, in-game, to other players for gold.
