Facebook will warn 87 million users, mostly in the U.S, that their data “may have been improperly shared with Cambridge Analytica by apps that they or their friends used”, the company just announced. Facebook CTO Mike Schoepfer tells TechCrunch that Facebook will warn these users with a notice atop the News Feed with information about what data of theirs might have been attained, and what they should do now. It will also show its new bulk app permissions removal tool atop the feed.
Schroepfer says that 87 million is the maximum number of users impacted, up from initial reports from the New York Times of 50 million people effected, as Facebook isn’t positive of how many people had their data misused. It likely doesn’t want to low-ball and have to revise the number upward later, as it did when it initially reported the Russian election interference ads were seen by 10 million users and later had to admit to congress it was actually 126 million when organic posts were included. Mark Zuckerberg plans to take questions from reporters about the changes during a 1:00pm Pacific conference call on the subject.
The changes come as part of a slew of announcements in the wake of the Cambridge Analytica scandal including new restrictions on Facebook API use and the immediate shut down of the old Instagram API that was slated for July, but which started to break developers’ apps this week. Facebook is now undergoing a deep audit of app developers that pulled a lot of data or that look suspicious, and Schroepfer promises Facebook will make further disclosures if it finds any situations similar to the Cambridge Analytica fiasco.
