According to the court, the judge arrived at this decision after concluding that Facebook needed to obtain the consent of these users before collecting information. “The judge ruled that this is personal data, which Facebook can only use if the Internet user expressly gives their consent, as Belgian privacy law dictates,” said the court in a statement.
Unsurprisingly, Facebook plans to appeal this decision on the grounds that the datr cookie helps keep the social network secure. “We’ve used the ‘datr’ cookie for more than five years to keep Facebook secure for 1.5 billion people around the world,” said a company spokeswoman. “We will appeal the decision and are working to minimise any disruption to people’s access to Facebook in Belgium.”
The issue surrounding Facebook’s use of the datr cookie first came to light in June of this year, when Belgium’s privacy watchdog, the Commission for the Protection of Privacy (CPP), took legal action against Facebook for delivering targeted advertisements to persons who didn’t use Facebook at all. Facebook defended these ads at the time by saying it was an industry-wide practice, but it is one that, anecdotally, has aroused the ire of many Internet users.
