At Defcon there is a event called the black ball in which you must wear somthing clever in order to get in. So me and my friends decided to wear black garbage bags and duct tape assorted items. One of the things I ended up making for myself was a bandana made out of duct tape. When I went up to my friends room (evil mofo) I noticed he had SF0 stickers. So I decided to put one on my bandana and there it remained for two days straight as I walked amoung thosands of people. It was not till later however that I realized that this might be good proof for this task so one could say I accidently spread SF0.
