If you’re a ninja assassin, a terrorist, an illegal street racer, or any other variety of violent outlaw, you shouldn’t look to YouTube for training anymore; you won’t find any there. The Google-owned video sharing site has revised its policies to specifically forbid videos that offer instructions on, “bomb making, ninja assassin training, sniper attacks, videos that train terrorists or tips on illegal street racing.” YouTube has long banned graphically violent content, but the new rule bans related instructional content even if the violence itself isn’t graphically depicted.
