Abstract :

[en] This paper examines the obligations of online service providers (OSPs) in the European Union (EU) to prevent and combat child sexual abuse material (CSAM). Through textual analysis of key EU legal frameworks, including the Digital Services Act and the Proposal for a Regulation laying down rules to prevent and combat child sexual abuse, this study assesses the illegal materials and OSPs targeted by these texts, their core obligations, and enforcement mechanisms. Findings indicate complex, overlapping regulatory requirements across EU law, highlighting tensions between child protection, technological limitations, and potential overreach affecting freedom of expression.
