How Facebook Decides If You See Nudity or Death (HBO)
Facebook employs 4,500 content moderators around the world. Moderators get two weeks of training and a stack of manuals to help them police the site for racism,
No racism? So, why is, eg, the racist, openly neonazi Dutch Nederlandse Volks-Unie party welcome and unmolested at Facebook?
No misogyny? Then, why Facebook censorship about women’s reproductive rights?
Then why the Facebook pages of the armed forces of the USA, Britain and many other countries; eg, of the army of Myanmar, busily killing Rohingya minority civilians?
VICE’s partners at The Guardian obtained more than a hundred of these manuals and they offer the first-ever look at the sometimes logical, sometimes inexplicable ways Facebook asks a few thousand people to help patrol its close to 2 billion users. This segment is part of the May 23rd  VICE News Tonight episode.
From daily The Morning Star in Britain:
Facebook ‘politically censoring’ Kurdish solidarity
Wednesday 18th October 2017
PRO-KURDISH activists accused Facebook of political censorship yesterday after it closed down a page expressing solidarity with Kurds in Syria.
The Leeds Friends of Rojava page was suspended after the site said it didn’t comply with Facebook’s “community standards.”
Kurdistan Solidarity Campaign (KSC) co-secretary Rosa Gilbert accused the social media giant of going out of its way to censor posts criticising Turkey and offering support for Kurds.
“Thanks to a leak a few years ago by one of Facebook’s ‘content moderators,’ we know that there is an internationally applied Facebook policy to censor maps of Kurdistan, criticisms of Turkey and Ataturk, and anything relating to the imprisoned Kurdish leader Abdullah Ocalan.”
She said the policy had broadened to include censoring posts supporting the [Syrian Kurdish] YPG which is not listed as a terrorist organisation in Britain although it is in Turkey.
“This should concern anyone with an interest in freedom of speech — why should someone writing a Facebook post in England face censorship because the Turkish government doesn’t like what you’re writing?”
So Facebook is not only helping the genocidal regime in Myanmar. They are censoring the Syrian Kurds, the main force effectively fighting the ISIS terrorists. They are doing that on behalf of Turkish autocrat Erdogan, often accused of helping ISIS. Erdogan, voted ‘dictator of the year’ jointly with the ISIS boss.
The political representatives of the American ruling class are engaged in a conspiracy to suppress free speech. Under the guise of combating “trolls” and “fake news” supposedly controlled by Russia, the most basic constitutional rights enumerated in the First Amendment are under direct attack: here.
Facebook CEO Mark Zuckerberg announced Friday that the world’s largest social network is initiating major changes aimed at deprioritizing news and political content on individual users’ news feeds in favor of “personal moments.” The change is the most significant effort to date to censor online information: here.
