well you know what?? i dont knw what happens at other countries but in pakistan even the photographers and the movie makers leak out pictures and videos at time for money sake!!! so its like you cant stop people actually plus if you are not doing it yourself and somebody else is posting your pictures then you are not the one to be blamed :)
When I was younger, my father NEVER let me dance in weddings in Pakistan, even if it was a simple luddi. He isn't a fan of dancing anyway, but his primary concern was the fact that these videographers have been known to sell such videos to sick men.
