And it’s not just particularly vulnerable people who fall victim either.
“[It’s] not the case that stupid people fall for romance scams - they can be very clever,” Professor Monica Whitty, a cyber-psychologist, explains. Scamalytics, a company which runs anti-scammer software for a number of the major dating sites, are trying to reduce online dating fraud by creating profiles of the average male and female con artist.
One of the most common techniques is to build up trust with the person by messaging for weeks or even months before suddenly having an emergency - the fake person being mugged but their daughter needing urgent surgery, for example - and asking for money.
But then they suddenly need money for rent too, then food, then medical fees, and it can quickly escalate.

Jane Googled him and found what looked like an authentic Linked In page and social media profiles as well as information on the projects he claimed to be working on, which seemed legitimate.
