Facebook is facing legal action from a 14-year-old from Northern Ireland who claims not enough was done to stop a naked picture of her being repeatedly posted.
Lawyers for the Belfast teenager say the image should have been blocked, but the web site insists it doesn't have to do that under European law.
She's suing Facebook and the person who uploaded the photo in what's believed to be the first case of its kind in the world.
The case is set to go to trial.
