MediaPost reports on a lawsuit against social-networking site LinkedIn (disclosure: I have a profile on the site).
Social-networking site LinkedIn has been sued for violating users’ privacy by allegedly leaking information about them to advertisers. In a complaint filed Friday with the U.S. District Court for the Northern District of California, San Francisco resident Kevin Low alleges that LinkedIn enabled ad networks and other third parties to discover his name and connect it to tracking cookies. […]
Low is seeking class-action status. A LinkedIn spokesperson said the company had not yet been served with a complaint, but knows about the case and believes it lacks merit. “We will defend ourselves vigorously,” the spokesperson said.
As with recent lawsuits against Facebook, the allegations against LinkedIn stem from the information in the referrer headers LinkedIn transmits to other sites. Low alleges that the referrer headers sent by LinkedIn include a unique identifier attached to a persistent LinkedIn cookie. The complaint also alleges that the unique identifiers allow users’ names to become known.
