The documents in question stem from a California court case between Facebook and Six4Three, which developed an app that let people pay to find pictures of users in swimsuits. Six4Three’s app was shut down in 2015 after Facebook changed its policies around the sharing of user data with third-party app developers.
Some of the documents had already been released by U.K. lawmaker Damian Collins, who has been probing Facebook’s data practices. NBC says the new documents were anonymously leaked to U.K. investigative journalist Duncan Campbell, and then shared with a handful of media outlets.
Facebook has said in the past that the documents were “cherry-picked” and misleading. NBC said it wasn’t able to confirm whether the documents reflect a “complete picture.”
Facebook was engulfed in scandal last year following revelations over the improper sharing of user data with now-defunct political consultancy Cambridge Analytica. Politicians around the world have called for increased regulation since, with some even suggesting a breakup of big tech firms, to combat the industry’s privacy problem.
