Featuring foreword from Maciej Szpunar, First Advocate General at the Court of Justice of the European Union and Professor at the University of Silesia in KatowiceThis book delivers a comprehensive examination of the legal systems that regulate the responsibilities of intermediaries for illegal online content in both the EU and the US. It assesses whether existing systems are capable of tackling modern challenges, ultimately advocating for the introduction of a double-sided duty of care, requiring online intermediaries to do more to tackle illegal content whilst also better protecting their users’ rights.
