Most anti-human trafficking efforts focus on breaking up sex sales. However, new in the journal Manufacturing & Service Operations Management is turning its attention to where trafficking truly begins—recruitment.
Using machine learning to analyze millions of online ads, researchers at the University of Pennsylvania have uncovered patterns that link deceptive job offers to sex trafficking networks. By mapping the connections between recruitment and sales locations, the study reveals a hidden supply chain—one that can now be exposed and interrupted earlier in the trafficking process.
"By combining data science with deep web analysis, we are helping to uncover trafficking networks and provide law enforcement with tools to intervene before exploitation occurs," says Hamsa Bastani of the University of Pennsylvania. "Our research reveals the hidden supply chains of sex trafficking, showing how recruitment often begins with false promises in vulnerable communities."
The study, "Unmasking Human Trafficking Risk in Commercial Sex Supply Chains with Machine Learning," finds that traffickers often lure victims from economically vulnerable areas, such as suburban communities, rather than large cities where most sex sales occur. This surprising discovery shifts the conversation about how trafficking networks operate and where interventions should be focused.
Instead of targeting only the urban centers where trafficking sales are most visible, researchers argue that more attention needs to be paid to recruitment hotspots in smaller, economically struggling communities.
According to Bastani, the research fills a critical gap in trafficking prevention efforts. "Unlike most studies that focus only on the sales side of trafficking, our research investigates the often-overlooked recruitment phase, providing a full view of trafficking supply chains," she explains. "By understanding how recruitment and sales connect at a network level, we can give law enforcement the insights needed to disrupt trafficking routes before exploitation occurs."
Conducted over several years, and leveraging real-world data from the deep web, the project combines technical innovation with real-world relevance. Its AI-driven insights can not only support law enforcement, but also enhance coordination between community organizations, social service providers and policy leaders working to protect at-risk populations.
"What makes this research so powerful is its scalability and real-world application," says Bastani. "We're providing a way for law enforcement to detect trafficking earlier in the process, potentially saving countless lives."
The researchers emphasize the importance of collaboration between researchers, social workers and policymakers.
"The insights we're generating can be applied beyond just law enforcement. Community organizations, nonprofits and policymakers can all use this information to protect at-risk populations," concludes Bastani.
As human trafficking continues to be a global issue, the researchers hope their work will lead to improved prevention measures and smarter policies. Their findings offer a new perspective on how trafficking networks operate and suggest a more comprehensive approach to combating exploitation at its source.
