Some have, others don’t. In general, the prankster movement on YouTube has been described as problematic many times because some guys concur for clicks by doing increasingly dangerous, often racist or mysoginic, stunts. Still, I don’t get how an adult person can think of removing STOP signs as a prank. But then again, I don’t know how people think abusing their kids on camera is a prank, like FamilyOf5 did.
