Facebook scandal 'hit 87 million users'

Facebook scandal 'hit 87 million users'
From BBC - April 4, 2018

Facebook believes the data of up to 87 million people was improperly shared with the political consultancy Cambridge Analytica - many more than previously disclosed.

The BBC has been told that about 1.1 million of them are UK-based.

The overall figure had been previously quoted as being 50 million by the whistleblower Christopher Wylie.

The details were revealed in a blog by the tech firm's chief technology officer, Mike Schroepfer.

The BBC has also learned that Facebook now estimates that about 305,000 people had installed the This Is Your Digital Life quiz that had made the data-harvesting possible. The previously suggested figure had been 270,000.

About 97% of the installations occurred within the US. However, just over 16 million of the total number of users affected are thought to be from other countries.

A spokeswoman for the UK's Information Commissioner's Office told the BBC that it was continuing to assess and consider the evidence before deciding what steps to take.

What is the controversy about?

Facebook has faced intense criticism after it emerged that it had known for years that Cambridge Analytica had collected data from millions of its users, but had relied on the London-based firm to self-certify that it had deleted the information.

Cambridge Analytica said it had bought the information from the creator of the This Is Your Digital Life app without knowing that it had been obtained improperly.

The firm says it deleted all the data as soon as it was made aware of the circumstances.

But Channel 4 News has since reported that at least some of the data in question is still in circulation despite Cambridge Analytica insisting it had destroyed the material.
