Do not recommend: How platforms reduce the visibility of some content, and why

Keynote talk by Tarleton Gillespie

Public debate about content moderation has overwhelmingly focused on removal: social media platforms deleting content and suspending users, or opting not to. But removal is not the only available remedy. Reducing the visibility of problematic content is becoming a commonplace part of platform governance. These platforms use machine learning classifiers to identify content that is misleading enough, harmful enough, offensive enough that, while they do not warrant removal according to the site’s guidelines, they warrant reducing their visibility by demoting them in algorithmic rankings and recommendations, or excluding them entirely. This talk documents this shift and explains how reduction works. Tarleton Gillespie raises questions about how and why platforms now use the decision of what and what not to recommend as a form of content moderation. Despite our distrust of platforms and how they have conducted content moderation up to this point, reduction policies may be the most mature step platforms have taken yet. On the other hand, this concentrates even more curatorial power in the hands of these elite, private, Western, profit-oriented intermediaries – using techniques that, at least so far, remain completely invisible to existing apparatuses of accountability.
