2. The Haren Riot
This is a case of life imitating art. Well, it can hardly be contested that the 2011 film Project X can be considered art, but the connection is nonetheless uncanny. It became known as Project X Haren. This was the biggest of them all, as the Facebook event went viral and the story was seen by millions due to its aftermath. This took place in, of course, the Dutch town of Haren. 34 arrests, smashed store windows, torched cars, public urination, looting, 36 injuries (including a police officer) and numerous burnings of chairs and other wooden things found in the town's public areas, beatings and bashing, anything and everything the rioters could get away with occurred. This was possibly the biggest (and only) riot organised and primarily advertised on a social network, as people took to Twitter and various blogs sites in addition to Facebook to spread the word. Rioters were imprisoned, fined and sentenced to community service. Journalists claimed they were harassed by the police more than the rioters when they were just doing their jobs. There were an estimated 3,000 people involved, more than three times anything else on this list. Further establishing the riot/party's claims as gigantic was the fact the clean up alone took hundreds of volunteers. The police were only brought in by the public's fear of this getting even more out of control, and those who didn't frequent social media must've felt there was an uprising or revolution happening. The origin of this? A 16 year old girl choosing to make her birthday party public so some of her friends could invite plus ones. Obviously this snowballed exponentially, with the public event being hijacked by 'ringleaders' who just wanted to carry out as much destruction as possible.
