'With this book, Giovanni Ziccardi confirms his leading position in the field of law and technology. Only a few scholars can claim, at the same time, his legal and technological understanding of the challenges related to online political hate speech. A must-read: it will finally make clear why the European constitutional scenario needs specific legal responses, in order to avoid, or at least mitigate, the risk of the rise of new extremisms on the Internet.'--Oreste Pollicino, Bocconi University, Italy
