Children face significant consumer risks when surfing online, related to, inter alia, embedded advertisements and privacy-invasive practices, as well as the exploitation of their incredulity and inexperience resulting in overspending or online fraudulent transactions. Behind the fun and playful activities available for children online lie complex revenue models, creating value for companies by feeding children’s data into algorithms and self-learning models to profile them and offer personalised advertising or by nudging children to buy or try to win in-app items to advance in the games they play. In this article we argue that specific measures against these forms of economic exploitation of children in the digital world are urgently needed. We focus on three types of exploitative practices that may have a significant impact on the well-being and rights of children – profiling and automated decision-making, commercialisation of play, and digital child labour. For each type, we explain what the practice entails, situate the practice within the existing legislative and children’s rights framework and identify concerns in relation to those rights.

Social media process (sometimes large amounts of) personal data of their users, usually on the basis of informed consent. In this article, a comparison is made between, on the one hand, existing practices of social media regarding informed consent for using personal data of users and, on the other hand, user expectations with regard to privacy and informed consent. The comparison is made on the basis of a set of criteria for informed consent distilled from an analytical bibliography. Next, the privacy policies of a selection of eight social network sites and user generated content sites are analyzed using this set of criteria for informed consent. User expectations regarding these criteria were derived from survey results of a large EU-wide online survey (N ¼ 8,621, 26 countries) on the awareness, values, and attitudes of social media users regarding privacy. We find that not all privacy policy criteria are important to users, but most criteria that are important to users can be found in most privacy policies.
