Cambridge Analytica whistleblowing reorders Facebook politics

Event Not yet reviewed This page has not yet been through the automated review pipeline.

Reporting on Cambridge Analytica's harvesting of Facebook profile data is followed by regulatory investigations in the UK and US and by new platform data policies.

Whistleblower Christopher Wylie describes how Cambridge Analytica obtained Facebook profile data through a personality-quiz app, and how the firm marketed psychographic targeting to clients including the 2016 Trump campaign.

Congressional hearings, a UK Information Commissioner’s Office report to Parliament, a Commons select committee inquiry, and FTC actions against both Facebook and Cambridge Analytica followed over the next eighteen months. Facebook also restricted third-party app access to friend data. How much the firm’s targeting actually moved votes remains contested and is not established by any of these proceedings.

    Information Commissioner's Office. Investigation into the Use of Data Analytics in Political Campaigns: A Report to Parliament. (2018). Published 6 November 2018. The ICO's own copy has been removed from ico.org.uk in a site reorganisation — both of its former media paths still return HTTP 404 — and this is a verbatim third-party mirror of the report to Parliament, whose text was read. Source for the ICO's findings on Cambridge Analytica and SCL Elections Ltd, which the report treats together ('Cambridge Analytica (CA) is a trading name of SCLE Elections Ltd'), and for the maximum £500,000 monetary penalty issued to Facebook under the pre-GDPR law.

    House of Commons Digital, Culture, Media and Sport Committee. Disinformation and 'fake news': Final Report (HC 1791, Session 2017-19). (2019). Ordered to be printed 14 February 2019; published 18 February 2019. Source for the parliamentary findings on data targeting and platform governance. This citation previously pointed at 179101.htm, which is the report's front matter — committee membership, powers and publication statement — and carries none of the findings attributed to it; it is now the full report, whose text was read (roughly 47,000 words, 69 mentions of Cambridge Analytica). publications.parliament.uk returns HTTP 403 to automated clients, so the payload was read from the recorded capture.

    U.S. Federal Trade Commission. In the Matter of Cambridge Analytica, LLC — Administrative Complaint, FTC Docket No. 9383. (2019). Filed 24 July 2019. ftc.gov serves this PDF to some automated clients and returns HTTP 403 to others, so a verified capture is recorded alongside it. States the FTC's allegations on the GSRApp: it 'harvested Facebook user profile data from approximately 250,000-270,000 Facebook users who directly interacted with the app, as well as 50-65 million of the "friends" in those users' social networks'.

Source for the record $5 billion penalty and the 20-year settlement order. The same release announces separate FTC actions against Cambridge Analytica, Alexander Nix and Aleksandr Kogan, none of which carried a monetary penalty; this is the only FTC monetary sanction against Facebook arising from this matter. ftc.gov returns HTTP 403 to some automated clients, so a verified capture is recorded.
