Needling Through the Threads: A Visualization Tool for Navigating Threaded Online Discussions

Navigating large-scale online discussions is difficult due to their rapid pace and high volume of content. Platforms like Reddit employ ``threads’’ to visually organize parallel discussions, but deep nesting obscures conversation flow. For moderators, this fragmentation compounds the difficulty of following evolving c…

"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 use it. To address this gap, we surveyed 110 moderators, who collec…

The Language of Approval: Identifying the Drivers of Positive Feedback Online

Positive feedback via likes and awards is central to online governance, yet which attributes of users' posts elicit rewards---and how these vary across authors and communities---remains unclear. To examine this, we combine quasi-experimental causal inference with predictive modeling on 11M posts from 100 subreddits. W…

The Chilling: Identifying Strategic Antisocial Behavior Online and Examining the Impact on Journalists

On social platforms like Twitter, strategic targeted attacks are becoming increasingly common, especially against vulnerable groups such as female journalists. Two key challenges in identifying strategic online behavior are the complex structure of online conversations and the hidden nature of potential strategies tha…

Venire: A Machine Learning-Guided Panel Review System for Community Content Moderation

Research into community content moderation often assumes that moderation teams govern with a single, unified voice. However, recent work has found that moderators disagree with one another at modest, but concerning rates. The problem is not the root disagreements themselves. Subjectivity in moderation is unavoidable,…

Creator Hearts: Investigating the Impact Positive Signals from YouTube Creators in Shaping Comment Section Behavior

Much of the research in online moderation focuses on punitive actions. However, emerging research has shown that positive reinforcement is effective at encouraging desirable behavior on online platforms. We extend this research by studying the ``creator heart'' feature on YouTube, quantifying their primary effects on…

Does Positive Reinforcement Work?: A Quasi-Experimental Study of the Effects of Positive Feedback on Reddit

Social media platform design often incorporates explicit signals of positive feedback. Some moderators provide positive feedback with the goal of positive reinforcement, but are often unsure of their ability to actually influence user behavior. Despite its widespread use and theory touting positive feedback as crucial…

"Positive reinforcement helps breed positive behavior": Moderator Perspectives on Encouraging Desirable Behavior

The role of a moderator is often characterized as solely punitive, however, moderators have the power to not only execute reactive and punitive actions but also create norms and support the values they want to see within their communities. One way moderators can proactively foster healthy communities is through positi…

Measuring Epistemic Trust: Towards a New Lens for Democratic Legitimacy, Misinformation, and Echo Chambers

Trust is crucial for the functioning of complex societies, and an important concern for CSCW. Our purpose is to use research from philosophy, social science, and CSCW to provide a novel account of trust in the `post-truth' era. Testimony, from one speaker to another, underlies many social systems. Epistemic trust, or…

Opportunities, tensions, and challenges in computational approaches to addressing online harassment

Given the scale at which online harassment occurs, researchers and practitioners alike have turned to computationally driven approaches to address it. However, because harassment is highly contextual and personal, designing effective solutions to this problem can be extremely challenging. This paper examines how haras…
