The Civic Labor of Volunteer Moderators Online
Open accessAbstract
Volunteer moderators create, support, and control public discourse for millions of people online, even as moderators’ uncompensated labor upholds platform funding models. What is the meaning of this work and who is it for? In this article, I examine the meanings of volunteer moderation on the social news platform reddit. Scholarship on volunteer moderation has viewed this work separately as digital labor for platforms, civic participation in communities, or oligarchy among other moderators. In mixed-methods research sampled from over 52,000 subreddit communities and in over a dozen interviews, I show how moderators adopt all of these frames as they develop and re-develop everyday meanings of moderation—facing the platform, their communities, and other moderators alike. I also show how this civic notion of digital labor brings clarity to a strike by moderators in July 2015. Volunteer governance remains a common approach to managing social relations, conflict, and civil liberties online. Our ability to see how communities negotiate the meaning of moderation will shape our capacity to address digital governance as a society.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
