This movie stired up quite a lot of dust in the Netherlands.
A girl in a small town called Haren wanted to set up a birthday party through Facebook. But she forgot to set in the settings that the party was only meant for friends. So within a couple of days more than 50.000 people said that they would come. The police and the mayor of Haren and the Dutch media (who really balloned the whole thing up to what it eventually became) kept saying that there was no party, and that no one should come. Off course people wanted to test that out and came anyway.
The end result? No party off course, but instead massive riots by normal everyday students and "professional" hooligans that turned the small town upside down leaving behind several severe injured people, Burned out cars, millions of Euro's in damages and quite possibly a change in the Dutch constitution so that the hooligans can be more easily tracked down and pay for the damages they did.
All because a innocent girl forgot to cross off a setting to make her party private on Facebook....
