Carole Cadwalladr and Professor David Carroll are both well known voices against what they see as Facebook’s wrongdoing. They were two founding members of a group called The Real Facebook Oversight Board, launched just three weeks before Facebook’s official Oversight Board started work last year.

Since then they’ve used the media to get their message out about everything from Facebook’s handling of the US election to the problem of vaccine misinformation on the company’s platforms.

Outside the Real Facebook Oversight Board, Carole is a well-known journalist who broke the Cambridge Analytica scandal, and David Carroll was seen in the Netflix documentary The Great Hack trying to get his data back from Cambridge Analytica.
