Crowdsourcing to Tackle Online Child Sexual Exploitation

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


This chapter examines the crowdsourcing model of Europol’s ‘Stop Child Abuse—Trace an Object’ (SCATO) platform on collecting tips provided by the public to tackle online child sexual exploitation. The chapter investigates the effectiveness of the platform with the most prominent sharing economy/crowdsourcing variables; low barrier accessibility, transaction cost and trust-building. Based on Europol documents and semi-structured elite interviews, the chapter’s core argument is that the SCATO provides a low barrier entry for the crowd to share tips with LEAs. However, to reduce the transaction cost of intelligence gathering, the item pictures shared on the platform should stimulate high-value reporting without compromising the victim’s anonymity. The platform also needs a clear guideline and feedback mechanism to encourage more public contribution.
