The NAACP urges “Log Out Facebook” protest after a Senate Intelligence Committee report found that Russians used the social media platform to target black voters to help Donald Trump in the 2016 presidential election.

“Facebook’s engagement with partisan firms, its targeting of political opponents, the spread of misinformation and the utilization of Facebook for propaganda promoting disingenuous portrayals of the African American community is reprehensible,” Derrick Johnson, NAACP President and CEO, said in a statement.

The civil rights organization has also returned a donation that it had recently received from Facebook. The group is also asking “its partners, social media followers and supporters” to log out of Facebook and Instagram for one week, starting on Dec. 18.

“The #LogOutFacebook is a protest – a way to signify to Facebook that the data and privacy of its users of color matter more than its corporate interests and that as the largest social network in the world,” the group said in a press statement.

The NAACP also hit Facebook for its lack of diversity among its employees. “It is Facebook’s corporate social responsibility to ensure that people of color are well represented in their workforce and recognize that users of color have a right to be protected propaganda and misinformation.”
