A Not For Sale project

About SlaveryMap

Human trafficking is usually described in abstract statistics: 50 million people in modern slavery worldwide. SlaveryMap makes the crisis concrete and local, the same job it was built to do since June 1, 2008.

Where it started

Not For Sale was founded in 2007 after co-founder David Batstone discovered that a Bay Area restaurant he ate at regularly was trafficking its own kitchen and wait staff. The case became national news, and it became personal: if slavery could hide inside a place he ate dinner every week, it could hide anywhere. At the time, most Americans still thought of slavery as history. SlaveryMap, launched June 1, 2008, was built to prove otherwise, one documented case at a time.

Open Source Activism

SlaveryMap ran on a philosophy Batstone called "Open Source Activism," borrowed from the tech industry: give people tools, not rules, and let local action connect to a global movement. Anyone could submit a case they'd seen or uncovered, and the map grew the way an open encyclopedia grows, case by case, refined by volunteers and editors. It drew interest from as far as the US Air Force Academy, one of the first tools that let ordinary people, not just researchers, put a place and a face to modern-day slavery in their own communities.

Closed in 2016, back today

By March 2016, SlaveryMap had logged 1,774 reports since launch. Not long after, the original site went quiet. Ten years later, it's back online, because the people who kept giving to Not For Sale never stopped believing this tool mattered.

From one map to a whole model

Not For Sale's work now runs on three tracks: people, planet, and social innovation. Internal notes from as early as 2010 were already using "people" and "planet" as working categories, years before "social innovation" had a name of its own. SlaveryMap came first. It remains the clearest example of what social innovation means here: not a program handed down from headquarters, but a tool that puts the ability to see the problem, and to act on it, directly in people's hands.

How cases are verified

Every decision behind SlaveryMap starts with the same question: does this put a survivor at risk? Cases are submitted by signed-in community members from credible news outlets, law enforcement and court records, and NGO reports. Before a case publishes, two other community members independently review it, to confirm the facts and to strip out anything that could identify or endanger the person behind them. Not For Sale sets the source standard and builds the platform; the community verifies. Locations are never shown precisely; every point on the map is generalized to city level by default. Verification here isn't a formality. It's the survivor's first line of protection, and nothing goes live until it clears that bar.

Open data, careful by design

Fighting trafficking is a collective effort, and it always has been for this project. By making verified, sourced data public, SlaveryMap puts investigative insight in many hands, while keeping survivor safety and privacy as the first constraint. Soon, that collective spirit comes fully back: the community is being invited to help find and add new cases again, the same instinct that built this map in the first place.
