Once again, the social network Facebook has become the target of a lawsuit – and once again it comes to the privacy issue. Two people have now filed a class action lawsuit in the U.S. San Jose. The accusation: Facebook is said to have deliberately spied private messages, and then passed the data collected for advertising purposes to companies. Specifically, this involves external links to third party sites, users have sent in private messages, such as the website “arstechnica.com” reports.Facebook to follow the links to get to the information for themselves can take advantage of personalized advertising. Addition the company shall keep on the linked pages for a “Like” button on the lookout. If there is such a button, the social network registered to visit the linked page as a “Like” – and thus makes a private communication visible. In its application, the company will therefore accused of deliberately breaking data protection and competition laws, such as the page writes. The company would not communicate the evaluation of private messages clearly enough.
