Mozilla reveals global harms posed by YouTube’s recommendation algorithm

In what Mozilla calls the “largest-ever crowdsourced investigation,” more than 37,000 YouTube users volunteered to find the extent of harms YouTube’s recommendation algorithm imposed on people via its recommendations. The algorithm, which drives 70% of watch time on the second-most-visited website in the world, was shown to be spreading misinformation and offensive content, and politicizing issues in 3,362 videos identified as “regrettable” coming from 91 countries.
