Facebook engineers admit they don’t know what happens to user data, lawsuit filings reveal

Two engineers at Facebook admitted that they do not know where user data ends up and that the task of figuring out where the data goes would require a team effort. The revelation was made during a discovery hearing in March, which was previously sealed, as part of the long-running lawsuit involving Cambridge Analytica.

The discovery hearing was led by Discovery Special Master Daniel Garrie, who was tasked with determining if Facebook should produce more documents for the case.

A transcript of the hearing, which was recently unsealed, and first reported by The Intercept, revealed that two Facebook engineers, Eugene Zarashow and Steven Elia, said that no engineer at the company knows where the user data ends up.
