This poster provides a longitudinal analysis of the infrastructure that underpins romance scams, tracing how the supporting systems and operational practices have evolved across an extended time frame. The discussion centers on the ecosystem surrounding deception campaigns, including messaging channels, platform usage, profile creation, and payment conduits, as well as the coordinating roles played by multiple actors. The aim is to map development over time, identify recurring patterns, and describe how shifts in technology and social behavior influence scam viability and resilience. A core theme is strategic legitimization: the ways in which scam operations appear credible and trustworthy to targets and observers. The poster notes mechanisms that contribute to perceived legitimacy, such as the use of consistent branding, believable personas, staged interactions, and the integration of seemingly legitimate services. It also considers how scammers adapt infrastructure to exploit trust-building opportunities and to evade detection, including cross-platform activity and the use of infrastructure components that resemble legitimate digital services. Findings are framed to inform researchers, platform operators, and policymakers about the evolution of the threat and potential countermeasures. The synopsis highlights the importance of recognizing long-running, adaptive patterns in romance-scam ecosystems and suggests directions for detection, risk communication, and harm reduction. The content is presented as a concise reference for attendees of the 2025 ACM SIGSAC Conference on Computer and Communications Security.
