Joyce Overheul (Netherlands, 1989) followed seventeen-year-old Rogier Hogervorst on Twitter and Instagram for a period of three months. During this time, he shared so much information about himself, in 5638 tweets and 137 photos, that Overheul was able to base a novel on him. The result, De drie maanden uit het leven van Rogier (Three months in the life of Rogier), emerged without Hogervorst possessing any knowledge of it. He wasn’t required to give permission; all the information used had been made public by Rogier himself. It was only when the book was finished, that Overheul informed him via Twitter. Hogervorst didn’t think his privacy had been breached, and he was even proud that Overheul had selected him. – Data rush, Noorderlicht
