The National Association for the Advancement of Colored People has asked people to boycott Facebook for a week following reports that the platform had been used by Russian agents to try to sway the minds of America’s black voters.

Two reports released Monday showed how millions of posts from fake Russian accounts ended up on Facebook, Instagram, YouTube and Twitter. But what was perhaps the biggest shock was that Russian agents had focused on sowing seeds of discontent in African-American communities.

Messages such as “I WON’T VOTE, WILL YOU?” were specifically aimed at black audiences. According to researchers at the University of Oxford and Graphika, the messages were either used to “discourage members from voting” or to put a more positive slant on Donald Trump.

NAACP has now returned a donation from Facebook and today started a #LOGOUTFACEBOOK protest. In a statement, it said Facebook had a responsibility to protect its users from being targeted by propaganda and misinformation.

“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,” said Derrick Johnson, the NAACP’s chief executive.

For its part, Facebook has agreed to give an update on a civil rights audit it started last May. That audit is headed by civil liberties leader Laura Murphy, who connected with various civil rights organizations in the U.S. to try to ascertain any problems.

Those problems, said Murphy, might relate to voter suppression, inclusion, diversity, content moderation and accountability. This year Facebook introduced new features to promote voting in the U.S.

“This report details the process for the civil rights audit I undertook; outlines my team’s work in partnership with Facebook over the last six months; and publicly shares progress that has been made, including policy changes, enforcement improvements, efforts to reduce voter suppression and increased transparency in advertising,” said Murphy.

That might not be enough to mollify the NAACP or steer Facebook out of a storm that just seems to keep getting worse. Black leaders have said Congress needs to kick Facebook into shape. “Last year we met with Facebook and other tech companies about this issue,” the Congressional Black Caucus said on the issue of racial targeting. “If they can’t stop the weaponization of their platforms, then Congress will.”
