Algorithmic Filtering is a good enough term but I think someone needs to dumb it down so everyone can understand exactly what's going on here. I may be overstating the obvious but I like to be completely clear. People tend to ignore wild eyed conspiracy nuts screaming on the sidewalk. I also strive for simplicity and readability. Just imagine the next paragraph is written all in caps. Something like...
"With the right kind of hacking Facebook can make a story almost disappear even though everyone assumes it's a tool to give the general public complete freedom to post whatever they want. News stories can be ignored just as easily as they are in mainstream outlets. Just as Google can target ads from what's written inside your email, Facebook has software that can read your posts and bury certain topics or at least control content from becoming viral to a certain extent. This is especially insidious because the very nature of social media gives people the illusion that it's some kind of tool to give a voice to the voiceless. Nothing can be further from the truth."
'For me, last night’s Ferguson "coverage" began when people started retweeting pictures of armored vehicles with heavily armored "robocops" on top of them, aiming their muzzle at the protesters, who seemed to number a few hundred. It was the fourth night after an unarmed black man, Michael Brown, was shot by a - still unnamed - police officer after a "jaywalking" incident. Witnesses say he died hands in the air, saying "don’t shoot".
'The first night Mike Brown was shot, a friend asked on Twitter whether this would ever make the national news. It deserved to be national news as multiple significant, ongoing crises intersect at Ferguson: the loss of jobs which hit these communities worst; the militarization of US police departments; race; chronic multi-generational poverty.
'But those very factors often make it less likely such places make the news, except as trouble spots. Places to be ignored. Avoided. "We" hear it only through official statements, often dismissing local concerns, painting them as looters, thugs, troublemakers.' (Medium article).
