Greatly Summarized, leaving it short:
1) Advertise to sell an account with no gametime, offering to go first.
2) Wait for a scammer to contact you, give him the account with INCORRECT Last name, and CD KEY (or say you don't have cd key).
3) Wait till you see your character online (or stay logged into account management and refresh till gametime is added). Recall character.
4) Profit - You got them to add gametime.
Note: Can also be done to a legit seller, but they'll recall their money and you'll have trouble with paypal.
