Many of us will have noticed 'friend' or 'follow' requests on our social media from strangers with profiles which don’t quite ring true. They mainly use cloned pictures, often taken from accounts of those in the US military. Zoe Kleinman investigates the global industry of romance scamming, which can have tragic consequences. Zoe hears from Lisa Forte, a cyber security expert from Red Goat Security, Professor Alan Woodward from Surrey University, and she goes into the tragic story of Renee Holland, as investigated by Jack Nicas of the New York Times. With thanks to the New York Times for their material.
