Facebook hired the audit’s leader, former American Civil Liberties Union executive Laura Murphy, in May 2018 to assess its performance on vital social issues.

Its 100-page report released Wednesday outlines a “seesaw of progress and setbacks” at the company on everything from bias in Facebook’s algorithms to its content moderation, advertising practices and treatment of voter suppression.

The audit recommends that Facebook build a “civil rights infrastructure” into every aspect of the company, as well as a “stronger interpretation” of existing voter suppression policies and more concrete action on algorithmic bias.

“While the audit process has been meaningful, and has led to some significant improvements in the platform, we have also watched the company make painful decisions over the last nine months with real world consequences that are serious setbacks for civil rights,” the audit report states.

Those include Facebook’s decision to exempt politicians from fact-checking, even when President Donald Trump posted false information about voting by mail.

Last month, Facebook announced it would begin labeling rule-breaking posts even from politicians going forward. But it is not clear if Trump’s previous controversial posts would have gotten the alert. The problem, critics have long said, is not so much about Facebook’s rules as how it enforces them.

More than 900 companies have joined an advertising boycott of Facebook to protest its handling of hate speech and misinformation.

Civil rights leaders who met virtually with Zuckerberg and other Facebook leaders Tuesday expressed skepticism that recommendations from the audit would ever be implemented, noting that past suggestions in previous reports had gone overlooked.
