Online platforms rely upon users or automated tools to fag toxic behaviors, the very frst step in online moderation. While much recent research has examined online moderation, the role of fag remains poorly understood. This question becomes even more urgent in automated moderation, where fagging becomes a primary source of human judgment. We conducted a qualitative study of fagging practices in League of Legends (LoL), a popular eSports game. We found stark diferences between how fag is designed to identify toxicity, and faggability, or how players use and appropriate fag. Players distrust fag, but also appropriate fag for instrumental purposes. Thus, faggability diverges decidedly from the conception of toxicity, and must be understood within the highly competitive gaming context of LoL. These fndings help shed light on the situated nature of faggability, the role of fag in online moderation, as well as implications for designing fag and moderation.
