Shortchanged: Uncovering and Analyzing Intimate Partner Financial Abuse in Consumer Complaints
要旨

Digital financial services can introduce new digital-safety risks for users, particularly survivors of intimate partner financial abuse (IPFA). To offer improved support for such users, a comprehensive understanding of their support needs and the barriers they face to redress by financial institutions is essential. Drawing from a dataset of 2.7 million customer complaints, we implement a bespoke workflow that utilizes language-modeling techniques and expert human review to identify complaints describing IPFA. Our mixed-method analysis provides insight into the most common digital financial products involved in these attacks, and the barriers consumers report encountering when doing so. Our contributions are twofold; we offer the first human-labeled dataset for this overlooked harm and provide practical implications for technical practice, research, and design for better supporting and protecting survivors of IPFA.

Stranger Danger? Investor Behavior and Incentives on Cryptocurrency Copy-Trading Platforms
要旨

Several large financial trading platforms have recently begun implementing ``copy trading,'' a process by which a leader allows copiers to automatically mirror their trades in exchange for a share of the profits realized. While it has been shown in many contexts that platform design considerably influences user choices---users tend to disproportionately trust rankings presented to them---we would expect that here, copiers exercise due diligence given the money at stake, typically USD 500--2\,000 or more. We perform a quantitative analysis of two major cryptocurrency copy-trading platforms, with different default leader ranking algorithms. One of these platforms additionally changed the information displayed during our study. In all cases, we show that the platform UI significantly influences copiers' decisions. Besides being sub-optimal, this influence is problematic as rankings are often easily gameable by unscrupulous leaders who prey on novice copiers, and they create perverse incentives for all platform users.

Supportive Fintech for Individuals with Bipolar Disorder: Financial Data Sharing Preferences for Longitudinal Care Management
要旨

Financial stability is a key challenge for individuals living with bipolar disorder (BD). Symptomatic periods in BD are associated with poor financial decision-making, contributing to a negative cycle of worsening symptoms and an increased risk of bankruptcy. There has been an increased focus on designing supportive financial technologies (fintech) to address varying and intermittent needs across different stages of BD. However, little is known about this population’s expectations and privacy preferences related to financial data sharing for longitudinal care management. To address this knowledge gap, we have deployed a factorial vignette survey using the Contextual Integrity framework. Our data from individuals with BD (N=480) shows that they are open to sharing financial data for long term care management. We have also identified significant differences in sharing preferences across age, gender, and diagnostic subtype. We discuss the implications of these findings in designing equitable fintech to support this marginalized community.

Trading as Gambling: Social Investing and Financial Risks on the r/WallStreetBets subreddit
要旨

Financial trading has become commonplace, involving the purchase and sale of securities such as stocks and bonds. While HCI research has investigated people’s financial literacy and decision-making and how to design for it, little is known as to how people form financial conversations on social media. To answer this question, we used a grounded theory approach to analyzing financial conversations in the YOLO (‘you only live once’) posts on the r/WallStreetBets subreddit (WSB), one of today’s largest financial online communities. We describe how WSB's discursive culture portrays its gambling-like, high-risk trading by likening trading to gambling, celebrating it, and normalizing financial risk-taking. We discuss the rise of social investing, including how individual investors’ affective relationships encourage their outsized risk-taking, as well as reflect on its looming financial risks, especially to already marginalized groups. Lastly, we propose implications for design and policymaking.

"Don't put all your eggs in one basket": How Cryptocurrency Users Choose and Secure Their Wallets
要旨

Cryptocurrency wallets come in various forms, each with unique usability and security features. Through interviews with 24 users, we explore reasons for selecting wallets in different contexts. Participants opt for smart contract wallets to simplify key management, leveraging social interactions. However, they prefer personal devices over individuals as guardians to avoid social cybersecurity concerns in managing guardian relationships. When engaging in high-stakes or complex transactions, they often choose browser-based wallets, leveraging third-party security extensions. For simpler transactions, they prefer the convenience of mobile wallets. Many participants avoid hardware wallets due to usability issues and security concerns with respect to key recovery service provided by manufacturer and phishing attacks. Social networks play a dual role: participants seek security advice from friends, but also express security concerns in soliciting this help. We offer novel insights into how and why users adopt specific wallets. We also discuss design recommendations for future wallet technologies based on our findings.
