Facebook said Thursday it had removed more than a billion fake accounts and taken action against millions of posts, photos and other forms of content that violated its prohibition against hate speech, terrorist propaganda and child exploitation, the latest sign that the social-networking giant faces an onslaught of online abuse as it builds new tools to spot it.

The report shows that Facebook still struggles to identify hate speech and bullying, in particular, even at a time when social media companies are grappling with the rising tide of racist, sexist and anti-Semitic content online and the United States is experiencing a rise in hate crimes.
