Why It's So Hard to Define What Online Hate Speech Is

Arbitrating the bounds of acceptable content on global tech platforms is an enormous task. Roughly 400 hours of content are uploaded to YouTube each minute. Facebook has more than 2 billion users posting updates, comments, and videos. Increasingly, these companies rely on software. Facebook-owned Instagram recently introduced an algorithm to zap comments from trolls. Both YouTube and Facebook have deployed software to filter terrorism-related content. YouTube delivers anti-ISIS content to users searching for ISIS-related videos with a tool known as the Redirect Method. Facebook says it can identify and wipe out clusters of users that might have terrorist ties. But the software remains imperfect, and so people are almost always involved, too.
