"Last year, Popular Science decided to close comments, citing studies that blamed them for the spread of misinformation. TechCrunch has changed platforms several times, to Livefyre, and back to Facebook comments. [...] It’s a Petri dish that grows trolls and frightens away those who actually want to contribute. At worst, an unmoderated comments section can contain threats and personal attacks, invalid criticisms and spam. [...] Moderation goes to great lengths to fix these problems. A moderator can ban dangerous trolls, protecting equitable commenters and increasing reply rates and time-on-site between those readers. [...] So, why did you want comments in the first place? Many organizations cite “engagement,” but what they actually mean is “action.” They want to motivate their readers to do something, whether that action is clicking a share button, emailing a tip, or contributing some form of user generated content.
