Many videos that show and promote drug abuse, alcohol abuse, and criminal behavior. Some of the worst and most extreme uploaders actually get paid by youtube for uploading videos showing and promoting these activities. There are supposed to be age restrictions in place on the site but these are rarely, if ever, enforced. I have personally had rolling battles with the site to even get them to take down videos of pre-teens smoking and promoting illegal substances. Adults can make their own choices but I would never let a child of mine use the site unless under direct supervision.
