YouTube's Algorithm Made Fake CNN Reports Go Viral

"YouTube channels posing as American news outlets racked up millions of views on false and inflammatory videos over several months this year," reports CNN. "All with the help of YouTube's recommendation engine."Many of the accounts, which mostly used footage from CNN, but also employed some video from Fox News, exploited a YouTube feature that automatically creates channels on certain topics. Those topic channels are then automatically populated by videos related to the topic -- including, in this case, blatant misinformation. YouTube has now shut down many of the accounts. YouTube's own algorithms also recommended videos from the channels to American users who watched videos about U.S. politics. That the channels could achieve such virality -- one channel was viewed more than two million times over one weekend in October -- raises questions about YouTube's preparedness for tackling misinformation on its platform just weeks before the Iowa caucuses and points to the continuing challenge platforms face as people try to game their systems.... Responding to the findings on Thursday, a CNN spokesperson said YouTube needs to take responsibility. "When accounts were deleted or banned, they were able to spin up new accounts within hours," added Plasticity, a natural language processing and AI startup which analyzed the data and identified at least 25 different accounts which YouTube then shut down. "The tactics they used to game the YouTube algorithm were executed perfectly. They knew what they were doing."
