The transatlantic Safe Harbour pact was ruled illegal last year. CNIL claims Facebook tracks non-users by placing cookies on their browser without them knowing, and is asking for the company to inform the users of their activity. On the other part, Facebook says a different thing: “Protecting the privacy of the people who use Facebook is at the heart of everything we do,” a Facebook spokeswoman told to the media. Last year, Facebook was forced to stop tracking non-users in Belgium and now Dutch, Spanish and German authorities have also prompted investigations on the social network’s practices. Regulators can now start taking legal action against companies still relying on Safe Harbour for approval to transfer data. If Facebook does not comply within three months it could be fined.
