When it rains, it pours - and Facebook’s utterly sodden year continues to be flooded by accusations of bad governance.

Mark Luckie, a black, former Facebook employee whose job it was to handle the firm’s relationship with “influencers”, put it quite plainly: “Facebook has a black people problem.”

His 2,500-word note, posted on Tuesday, outlines what he sees as a culture that talks about inclusion, but does not practise it. In some buildings at the company, Mr Luckie said, there were “more ‘Black Lives Matter’ posters than there are actual black people”.

He goes on to outline how he, and other black employees, often felt uncomfortable at work about how Facebook’s black users are also being unfairly treated:

Black staffers at Facebook know that by raising our voices we risk jeopardising our professional relationships and our career advancement.

Black people are finding that their attempts to create ‘safe spaces’ on Facebook for conversation among themselves are being derailed by the platform itself.

Non-black people are reporting what are meant to be positive efforts as hate speech, despite them often not violating Facebook’s terms of service.”
