Recital 69 DSA

When recipients of the service are presented with advertisements based on targeting techniques optimised to match their interests and potentially appeal to their vulnerabilities, this can have particularly serious negative effects. In certain cases, manipulative techniques can negatively impact entire groups and amplify societal harms, for example by contributing to disinformation campaigns or by discriminating against certain groups. Online platforms are particularly sensitive environments for such practices and they present a higher societal risk. Consequently, providers of online platforms should not present advertisements based on profiling as defined in Article 4, point (4), of Regulation (EU) 2016/679, using special categories of personal data referred to in Article 9(1) of that Regulation, including by using profiling categories based on those special categories. This prohibition is without prejudice to the obligations applicable to providers of online platforms or any other service provider or advertiser involved in the dissemination of the advertisements under Union law on protection of personal data.
