"Think about it like you're a firefighter": Understanding How Reddit Moderators Use the Modqueue

On Reddit, the moderation queue (modqueue) is the platform’s primary interface for reviewing user-reported and automatically flagged content. Despite its central role in Reddit’s community-reliant moderation model, little is known about how moderators actually use it in practice. To address this gap, we surveyed 110 moderators, who collectively oversee more than 400 subreddits, to understand how the modqueue fits into their workflows and what its design enables or constrains. We find substantial variation in modqueue use: some moderators treat it as a daily checklist, others use it to identify patterns or emerging issues, and many routinely leave the interface to gather additional context or coordinate with teammates. Respondents also described persistent challenges, including coordination issues such as collisions, incomplete or noisy information signals, and friction created by fragmented interface versions and reliance on third-party tools. Taken together, we show the modqueue is neither a one-size-fits-all solution nor sufficient on its own for supporting moderator review. We outline opportunities for more modular, better-integrated moderation infrastructures that support both item-level review and broader governance activities, and that better align with the collaborative and value-driven nature of volunteer moderation on Reddit.
