The ad suggests that using your mobile phone to send naked pictures of yourself to someone who promises not to share them is a very bad idea. It features a girl, sitting in her bedroom, using Bob Dylan-style message boards to tell her tale, as her image replicates on dozens of phones behind her.
The campaign — from Cosette, Vancouver — will also appear in cafes, on school posters, transit shelters and more.
It was inspired by Amanda Todd, a 15-year-old who committed suicide after being bullied at school following a webcam incident.
The tagline is, "There is no such thing as 'just one photo.'"
