Facebook estimated that at any given time fake accounts comprise about 5 percent of its 2.4 billion monthly active users.

The report also illustrated the efforts Facebook has taken to enforce other content policies as well as the massive scale of abuse that the company must monitor and crack down on.

Facebook has reported a steady increase in the amount of hate speech it cracks down on. In the first quarter, it removed 4 million pieces of content it deemed had violated its prohibition against hate speech, compared with 3.3 million in the last quarter of 2018.

The social network attributes the increase to the investments it has made in artificial intelligence designed to detect hate speech.
