Facebook staff raised concerns about Cambridge Analytica in September 2015, per court filing

Last year a major privacy scandal hit Facebook after it emerged CA had paid GSR, a developer with access to Facebook’s platform, to extract personal data on as many as 87 million Facebook users without proper consent.

Cambridge Analytica’s intention was to use the data to build psychographic profiles of American voters to target political messages — with the company initially working for the Ted Cruz and later the Donald Trump presidential candidate campaigns.

Facebook is seeking to have documents pertaining to the case sealed, while the District argues there is nothing commercially sensitive to require that.

In its opposition to Facebook’s motion to seal the document, the District includes a redacted summary of the “jurisdictional facts” it says are contained in the papers Facebook is seeking to keep secret.

Facebook repeated the same line to the U.K.’s Digital, Media and Sport committee last year, over a series of hearings with less senior staffers.

Damian Collins, the chair of the DCMS committee tweeted yesterday that the new detail could suggest Facebook “consistently mislead” the British parliament.

The DCMS committee has previously accused Facebook of deliberately misleading its enquiry on other aspects of the CA saga, with Collins taking the company to task for displaying a pattern of evasive behavior.

The incident displays the fundamental weakness of Facebook in managing its responsibilities to the people whose data is used for its own commercial interests.
