This investigation was launched following a complaint initially made by the French Data Protection Authority.”The inquiry examined LinkedIn’s processing of personal data for the purposes of behavioural analysis and targeted advertising of users who have created LinkedIn profiles (members),” according to a DPC press release. “The decision includes a reprimand, an order for LinkedIn to bring its processing into compliance, and administrative fines totalling €310 million.”LinkedIn asserts that it believes it has been in compliance with the rules but acknowledges that it will work to ensure its ad practices meet the requirements.
