In this day of digital technology, there are still those who use good old voodoo magic for revenge. The VoodooBuddy exists to upgrade and bring voodoo to the 21st century.
Just enter the information of your most despised rival, then poke away at the doll as often as you like. Users prick the networked voodoo doll with pins, and the output is annoying spam, disturbing email images, and disquieting text messages and phone calls channeled to the victim. But if you go too far in your curses, it will take a photo and send it to the victim instead, in order to reverse the curses and expose you.
