The Irish Council for Civil Liberties is filing a lawsuit against the Interactive Advertising Bureau Tech Lab for alleged EU General Data Protection Regulation violations, Reuters reports. The ICCL will file the suit in Hamburg, Germany, arguing real-time bidding systems, used by IAB member companies, harvest users’ personal data. “A retailer might use the data to single you out for a higher price online. A political group might micro-target you with personalised disinformation,” said ICCL Senior Fellow Johnny Ryan.
