Social media platforms and their governance policies often fail marginalized users in high-stakes contexts, including war, violent attacks, human rights violations, humanitarian crises, and situations of systemic oppression. Through interviews, autoethnography, and digital ethnography, this paper presents three case studies from Venezuela, Nigeria, and the United States to examine how marginalized populations engage with social media in non-normative ways. We analyze how platform design and policies intersect with participants’ identities, marginalization, and labor. Our central finding is that users’ urgent infrastructural and contextual needs are often overlooked, revealing structural flaws in social media design that mimic physical-world power asymmetries. In response, users develop innovative workarounds, engage in self-censorship, and adopt coping strategies, undertaking additional, often invisible, sociotechnical repair work that reinforces their precarity. To address these complex needs, we urge social media companies to collaborate with marginalized users to integrate alternative infrastructural features, such as emergency response tools and exit mechanisms for wellbeing.

This paper investigates how deeply entrenched offline gender norms and patriarchal power structures constrain and shape participation within Tech Aids, a large Facebook community in Pakistan focused on peer-to-peer technical help and e-commerce transactions. Through a qualitative study involving 14 months of participant observation and 20 semi-structured interviews (11 male, 9 female), we document significant gendered disparities: women exhibit lower public engagement, driven primarily by heightened privacy concerns, fear of harassment, and perceived male gatekeeping. Our analysis reveals that traditional socio-cultural restrictions on women’s mobility and constrained interactions with unfamiliar men in physical tech marketplaces are directly mirrored in the online Tech Aids environment. To manage these risks, women actively engage in practices of digital purdah, using workarounds like proxy-posting through male relatives to maintain both technical access and cultural modesty. By linking these offline barriers to online participation strategies, this study provides a vulnerability-centric framework and actionable design insights for creating more equitable online tech communities that explicitly address complex, deeply rooted socio-cultural constraints in non-WEIRD contexts.

Peer review determines which scholarship is legitimized; however, review biases often disadvantage scholarship that diverges from the norm. Human–Computer Interaction (HCI) lacks a systemic inquiry into how such biases affect underrepresented Global South (GS) scholarship. To address this critical gap, we conducted four focus groups with 16 HCI researchers studying the GS. Participants reported experiencing reviews that confined them to development research, dismissed their theoretical contributions, and questioned situated knowledge from GS communities. Both as authors and reviewers, participants reported experiencing the epistemic burden of over-explaining why knowledge from GS communities matters. Further, they noted being tokenized as “cultural experts” when assigned to review papers and pointed out that the hidden curriculum of writing HCI papers often gatekeeps GS scholarship. Using epistemic oppression as a lens, we discuss how review practices marginalize GS scholarship and outline actionable strategies for nurturing equitable epistemological evaluation of HCI scholarship.

In order to sustain everyday life in India during pandemic induced lockdowns, home service gig platforms materialized to provide essential services for urban society. As unemployment worsened, these gig platforms also emerged as key sources of paid work for gig workers, with some platforms promising an unusual degree of health and financial support for their gig workforce. Through semi-structured interviews, we examine how women beauty workers engaged with the infrastructural promise extended by home service gig platforms during the pandemic. While gig platforms promoted the potential of stable income and social security in the context of the Global South, we investigate the reality behind this image. We find that various breakdowns, from miscommunication around localized travel restrictions to limited platform helpline access, introduces day-to-day unpredictability for gig workers, hindering access to paid work as well as other platform extended benefits. We suggest that home service gig platforms actually serve as 'faux infrastructure,' in which the privatized logics work to enclose public value, while pushing the burden of access onto gig workers who must perform additional, often unpaid labors, in order to fill last-mile service gaps.

In August 2020, the U.S. President issued an executive order to ban the Chinese-based social platform WeChat, alleging that WeChat posed a national security risk. WeChat is a vital application for Chinese diasporic communities in the United States. The ban's status was uncertain for several months before it was temporarily halted and later revoked in 2021. Through interviews with 15 WeChat users and online participant observation, this study examines the anticipated impacts of the potential WeChat ban and participants' reactions. We find that participants described negative consequences of the potential ban, including adverse network and economic effects and disruption of community-building efforts. We also find that many participants considered WeChat to be critical infrastructure in the United States, as it has become an indispensable part of their daily lives. To frame participants' experiences, we introduce the concept of infrastructural migration-the process of users relocating to another digital media service that embodies the properties and functions of infrastructure or moving to an assemblage of different applications that meet their infrastructural needs separately. We then discuss implications for designing for infrastructural migration and future considerations for HCI research with diasporic communities.

Venezuela is in the midst of a humanitarian crisis. In addition to food and medicinal shortages, violent crime has risen dramatically since 2014, spurring a mass exodus from the country. In order to cope with persistent material, informational, and digital infrastructural breakdowns that their friends and family in Venezuela are facing, members of the Venezuelan diaspora have turned to social media platforms to support people they left behind. Through semi-structured interviews and participant observation, I uncover the ways participants form a critical infrastructure for people in Venezuela. I describe participants' actions as infrastructural care --- infrastructural action as a form of caring for others at a distance through the ongoing management of resources, relationships, and infrastructures. Infrastructural care consists of relational, negotiated, and dialectic actions that provide critical support while also generating ongoing tensions as participants are geographically separated from the crisis and, through their involvement, are forced to confront their own experiences of trauma. In addition to proposing the lens of infrastructural care, this paper contributes to our understandings of the ways people cope with an ongoing humanitarian crisis at a distance and how social media platforms fit in with wider ecologies of efforts.

In Cuba, where internet access is severely constrained, technology enthusiasts have built StreetNet (SNET), a community network (CN) that has grown organically, reaching tens of thousands of households across Havana. Through fieldwork conducted in 2016 and 2017, we investigate participants' strategies as they engage with a network where the material elements---cables, switches, nanos, and servers---are regularly breaking down. Drawing on maintenance and care (M&C) scholarship, we present an in-depth investigation of the management and anticipation of breakdowns in SNET, foregrounding the deeply relational nature of repair work, collective efforts required for SNET's M&C, and the values and motivations underpinning these practices. Our paper contributes a unique perspective on how CNs are run locally and organically, outlining considerations for how interventions along these lines might be more suitably designed. We also complicate perspectives of innovation through a discussion of cultural ideologies and tensions underpinning M&C practices.

We contribute a case study of El Paquete Semanal or "The Weekly Package" -- the pervasive, offline internet in Cuba. We conducted a qualitative inquiry of El Paquete through extensive fieldwork---interviews and observations---in Havana, Cuba. Our findings highlight the human infrastructure that supports this offline internet, rendered visible through the lens of articulation work. By offering an in-depth perspective into these workings of El Paquete, we aim to challenge established notions of what an (or the) internet "should" look like in more and less "developed" contexts. We highlight how El Paquete is a non-standardized and non-neutral internet, but still human-centered. We also offer an enriched understanding of how an entirely offline internet can provide expansive information access to support leisure and livelihood, additionally serving as a locally relevant platform that affords local participation.

Since 2014, Venezuela has experienced severe economic crisis, including scarcity of basic necessities such as food and medicine. This has resulted in over-priced goods, scams, and other forms of economic abuse. We present an investigation of Venezuelans' efforts to form an alternative, Solidarity Economy (SE) through Facebook Groups. In these groups, individuals can barter for items at fair prices. We highlight group practices and design features of Facebook Groups which support solidarity or anti-solidarity behaviors. We conclude by leveraging design principles for online communities presented by Kollock to present strategies to design more effective SEs in environments of low trust.

Since March 2015, the public squares of Havana have been transformed from places where people stroll and children play to places where crowds gather to try to connect to the internet at all hours of the day and night. We present a field investigation of public WiFi hotspots in Havana, Cuba, and examine the possibilities of internet access these limited and expensive hotspots present to individuals, many of who are experiencing the internet for the first time. Drawing on fieldwork conducted in 2015-2016, we underscore the reconfigurations that have resulted from this access, as evolving internet users reconfigure their interactions with place, time, and individuals in their efforts to locate the internet. We also discuss the implications our findings have for the design of internet access interventions in Cuba and in other low-resource environments across the world, as well as the broader implications for social computing across diverse geographies.

When social networking sites give users granular control over their privacy settings, the result is that some content across the site is public and some is not. How might this content--or characteristics of users who post publicly versus to a limited audience--be different? If these differences exist, research studies of public content could potentially be introducing systematic bias. Via Mechanical Turk, we asked 1,815 Facebook users to share recent posts. Using qualitative coding and quantitative measures, we characterize and categorize the nature of the content. Using machine learning techniques, we analyze patterns of choices for privacy settings. Contrary to expectations, we find that content type is not a significant predictor of privacy setting; however, some demographics such as gender and age are predictive. Additionally, with consent of participants, we provide a dataset of nearly 9,000 public and non-public Facebook posts.

We present a study of internet use and its forced non-use in Bangladesh. In light of current initiatives by state and industry actors to improve internet access and bridge the 'digital divide' for under-served, under-resourced, and underrepresented communities across the world, we offer a situated, qualitative perspective on what the current state of internet use looks like for select social groups in Bangladesh. We analyze how a state-imposed ban attempted to affect the nonuse of particular web-based services and how the affected populations found or did not find workarounds in response. We also discuss takeaways for researchers as well as industry and state actors studying and working towards more equitable access to the internet in the 'developing' world.

Although the Cuban government has tightly controlled information access for more than half a century, a small number of Cubans have access at work. In this paper, we examine Internet and social media use by early adopters in Cuba in early 2015, as we enter a time of potential change. Specifically, we explore Cubans' access limitations and the activities they do online, as well as what Internet access means to them. We conducted interviews with 12 Cuban Internet users and observed their social media use. Our findings suggest that access limitations and slow network speeds greatly restrict Cubans' Internet use. To counter these limitations, Cubans are collaborative, often conducting online research and posting photos for friends with less access. Based on these findings, we propose future work to help meet Cuban citizens' information needs.

This qualitative study of parents in financially depressed communities in westside Atlanta examines parents' access to information technology and out-of-school learning resources through five dimensions of digital divide: technical apparatus, autonomy, social support, skill, and purpose. The context of this study is a broader research agenda to explore how technology impacts parents' knowledge and use of out-of-school learning resources for their children in low socioeconomic status neighborhoods. The findings contribute to a growing body of research on marginalized groups and provide a rich description of parents' digital access and technology practices in the context of education. Finally, we identify design implications that are specific to this community and can be extended to similar populations to support parents in finding more learning opportunities.

CSCW systems are playing an increasing role in activism. How can new communications technologies support social movements? The possibilities are intriguing, but as yet not fully understood. One key technique traditionally leveraged by social movements is storytelling. In this paper, we examine the use of collective storytelling online in the context of a social movement organization called Hollaback, an organization working to stop street harassment. Can sharing a story of experienced harassment really make a difference to an individual or a community? Using Emancipatory Action Research and qualitative methods, we interviewed people who contributed stories of harassment online. We found that sharing stories shifted participants' cognitive and emotional orientation towards their experience. The theory of "framing" from social movement research explains the surprising power of this experience for Hollaback participants. We contribute a way of looking at activism online using social movement theory. Our work illustrates that technology can help crowd-sourced framing processes that have traditionally been done by social movement organizations.
