Abstract
Background: In this article, we address the use of metatags as a form of community knowledge formation and gatekeeping within digital platforms. Situating the case: The subReddit KotakuInAction is a well-known hub of the GamerGate community on Reddit, but one that has avoided the bans common to other aggressive subReddits and GamerGate communities on platforms such as 4chan and GitHub. We contextualize the aggressive nature of the subReddit and the reasons why participants' uses of metatags are meaningful for understanding subReddit culture and moderation practices. Methodology: To better understand the destructive behavioral patterns of KotakuInAction, we coded for the frequency of certain behaviors, such as linking and tagging, as well as the shift in certain keywords and vocabularies between the front facing or predetermined tags and the user-customized or admin-altered tags. We also examined how tags shifted over time and whether certain users dominated particular tags. About the case: What we found was a hybrid culture on KiA that applied Chan culture values and flaming, but increasingly localized the behavior to KiA rather than direct readers out of the site. We also found key shifts in topics away from gaming and activism toward broader complaints about social justice. In addition, we found that a tiny core group of nine influencers (out of tens of thousands of users) accounted for 20% of the top conversations. Conclusions: We suggest a closer examination of how communities self-organize around meta naming structures. Knowledge of this activity can help with predicting and engaging with aggressive and hostile communities by describing how topics shift over time, how they adapt to platform moderation, and who the influencers within a community might be.
