Be careful though. If Google find out what you've been doing it's highly likely they'll never let you use their AdSence service again, even if you go clean and don't advertise on Warez sites or anything.
If I where you I would find another source of adverts, or manually sell ad space if you're erally wanting to do this, but I advice you don't as you could get in a lot of trouble if you have links to copyrighted stuff on that board
