What it is about
Question: is the operator of a classified ads site the controller for personal data in adverts placed by users, and can it rely on the intermediary liability exemptions of the e-Commerce Directive? Ruling: the operator is controller and must, before publication and through technical and organisational measures, identify adverts containing special category data, verify that the advertiser is the data subject and otherwise refuse publication, unless explicit consent or another Article 9(2) exception is demonstrated. It must also take security measures against copying of such adverts to other sites. The e-Commerce Directive exemptions do not apply to these GDPR obligations.
What this means in practice
Platforms, marketplaces and forums where users can post content with other people's personal data must build in a pre-publication check for sensitive content, with identity verification of the poster and a refusal mechanism. Technical measures against scraping and republication are also part of the security duty. The defence that you are merely a neutral conduit does not work under the GDPR.
