Today Facebook reported that information for up to 87 million people may have been improperly obtained by research company GSR. Cambridge Analytica licensed data for no more than 30 million people from GSR, as is clearly stated in our contract with the research company. We did not receive more data than this.
We did not use any GSR data in the work we did in the 2016 US presidential election.
Our contract with GSR stated that all data must be obtained legally, and this contract is now a matter of public record. We took legal action against GSR when we found out they had breached this contract.
When Facebook contacted us to let us know the data had been improperly obtained, we immediately deleted the raw data from our file server, and began the process of searching for and removing any of its derivatives in our system.
When Facebook sought further assurances a year ago, we carried out an internal audit to make sure that all the data, all derivatives, and all backups had been deleted, and gave Facebook a certificate to this effect.
We are now undertaking an independent third-party audit to demonstrate that no GSR data remains in our systems.
