Content moderation and the digital transformations of gatekeeping

Abstract This essay provides an overview of the current state of content moderation on social media platforms. The question the essay addresses is why there are a number of unresolved issues in tackling dysfunctional content. The argument is that there are two intersecting new phenomena which make effective content moderation difficult: one is that social media platforms lack the gatekeeping of content that was characteristic of traditional news media. The second is that the regulation of this un‐gatekept content is still unsettled; it falls between social media companies that span the globe and the regulations or absence thereof bounded by nation‐states. To understand both, an analysis restricted to law and regulation is insufficient. Instead, it is necessary to examine the role of media systems in society in a holistic way, and in a way that distinguishes between gatekept media and the absence of gatekeeping or new forms of gatekeeping. Such a broader account points to why the institutionalization of content moderation is likely to be a protracted and uneven process. The conclusion spells out how the tensions that have arisen with new media could be resolved, but also why they are likely to remain imperfectly resolved.
