Applied machine learning (ML) has not yet coalesced on standard practices for research ethics. For ML that predicts mental illness using social media data, ambiguous ethical standards can impact peoples’ lives because of the area’s sensitivity and material con- sequences on health. Transparency of current ethics practices in research is important to document decision-making and improve research practice. We present a systematic literature review of 129 studies that predict mental illness using social media data and ML, and the ethics disclosures they make in research publications. Rates of disclosure are going up over time, but this trend is slow moving – it will take another eight years for the average paper to have coverage on 75% of studied ethics categories. Certain practices are more readily adopted, or "stickier", over time, though we found pri- oritization of data-driven disclosures rather than human-centered. These inconsistently reported ethical considerations indicate a gap between what ML ethicists believe ought to be and what actually is done. We advocate for closing this gap through increased trans- parency of practice and formal mechanisms to support disclosure. 

Online volunteers are a crucial labor force that keeps many for-profit systems afloat (e.g. social media platforms and online review sites). Despite their substantial role in upholding highly valuable technological systems, online volunteers have no way of knowing the value of their work. This paper uses content moderation as a case study and measures its monetary value to make apparent volunteer labor’s value. Using a novel dataset of private logs generated by moderators, we use linear mixed-effect regression and estimate that Reddit moderators worked a minimum of 466 hours per day in 2020. These hours are worth 3.4 million USD based on the median hourly wage for comparable content moderation services in the U.S. We discuss how this information may inform pathways to alleviate the one-sided relationship between technology companies and online volunteers. 

Online volunteers are an uncompensated yet valuable labor force for many social platforms. For example, volunteer content moderators perform a vast amount of labor to maintain online communities. However, as social platforms like Reddit favor revenue generation and user engagement, moderators are under-supported to manage the expansion of online communities. To preserve these online communities, developers and researchers of social platforms must account for and support as much of this labor as possible. In this paper, we quantitatively characterize the publicly visible and invisible actions taken by moderators on Reddit, using a unique dataset of private moderator logs for 126 subreddits and over 900 moderators. Our analysis of this dataset reveals the heterogeneity of moderation work across both communities and moderators. Moreover, we find that analyzing only visible work – the dominant way that moderation work has been studied thus far – drastically underestimates the amount of human moderation labor on a subreddit. We discuss the implications of our results on content moderation research and social platforms. 

Parental control applications are designed to help parents monitor their teens and protect them from online risks. Generally, parents are considered the primary stakeholders for these apps; therefore, the apps often emphasize increased parental control through restriction and monitoring. By taking a developmental perspective and a Value Sensitive Design approach, we explore the possibility of designing more youth-centric online safety features. We asked 39 undergraduate students in the United States to create design charrettes of parental control apps that would better represent teens as stakeholders. As emerging adults, students discussed the value tensions between teens and parents and designed features to reduce and balance these tensions. While they emphasized safety, the students also designed to improve parent-teen communication, teen autonomy and privacy, and parental support. Our research contributes to the adolescent online safety literature by presenting design ideas from emerging adults that depart from the traditional paradigm of parental control. We also make a pedagogical contribution by leveraging design charrettes as a classroom tool for engaging college students in the design of youth-centered apps. We discuss why features that support parent-teen cooperation, teen privacy, and autonomy may be more developmentally appropriate for adolescents than existing parental control app designs. 

Many decisions about social, economic, and personal life are heavily data-driven. At the same time, data has become increasingly quantified, and available to people and institutions in positions of power, often with little introspection or reflection on its positive uses or harmful misuses. This panel will inspect CSCW’s role in identifying constructive and appropriate uses of data and its responsibility for protecting against harms and inequalities perpetuated by misuse. The panel will present a series of debates about quantification of data, data surveillance, organizational data use, and policy making. An overarching theme throughout the set of debates is interrogating CSCW’s role in extending critical scholarship on power and justice towards academic, policy, and industry impact.
