"We are removing any and all mentions of the potential whistleblower's name and will revisit this decision should their name be widely published in the media or used by public figures in the debate," Facebook said in a statement in which they claim it violates their "coordinating harm" policy which prohibits content 'outing of witness, informant, or activist.'
On Wednesday, the social media giant removed ads naming Ciaramella which had been viewed several hundred thousand times according to the Washington Post.
On Friday, Breitbart's Allum Bohkari reported that the news outlet's posts containing references to Ciaramella had been scrubbed from the site.
Wednesday evening, Facebook removed Breitbart posts reporting on the fact other respected news outlets have reported the identity of the alleged whistleblower is Eric Ciaramella. Any Facebook user who attempts to click on that article on Facebook is now given a message that says, "this content isn't available at the moment."
To be clear, Breitbart did not "out" the alleged whistleblower but did provide additional relevant reporting about him; he is, after all, a public figure, having served on the National Security Council. Moreover, his name has been used in the Mueller report (p283) and Ambassador Bill Taylor's testimony.
