I'm not sure why they're still doing the WoS. The goal to raise security awareness among attendees seems to have been achieved or obviated. Now it just seems like a game where people try to put funny, pornographic, or commercial images up. Expenses are up, benefits are down, where's the end point? I even think a case could be made that they're encouraging the display of porn by turning it into this sort of cat-and-mouse game.
