The Invisible Metropolis: A Quantitative and Qualitative Analysis of Digital Infidelity Communities on Reddit (2026)

This research brief examines the rapid growth of "affair-seeking" communities on Reddit, identifying a combined weekly active population of 186,000 users across key subreddits. By comparing digital engagement metrics to major U.S. metropolitan hubs, the study reveals a significant migration of individuals seeking extracommunal intimacy due to marital "Dead Bedrooms" and emotional neglect. The paper categorizes the 10 primary systemic frustrations of these anonymous forums—ranging from OPSEC anxiety to "ghosting"—and proposes clinical implications for specialized digital infidelity platforms.
