I was poking around google last night to see if I could find any of my images in use and came across a forum that is full of watemarked images. Mostly from IS, SS and Veer.
It appears to be a game played out within a forum. It looks to be harmless fun and not hardcore pirating but I thought I would post a link and make the stock community aware of it.

Im not sure exactly how the game is played or whats going on but if you click on any of the game round threads you'll find the watermarked images.
