Nancy*, a 47-year-old single mother from North Yorkshire was conned out of over £350,000 that way: “I wasn't comfortable, and then I got so far in I couldn't get myself out, and I didn't want to walk away having lost £50,000 or what-have-you, so you keep going in the hope that you're wrong and this person is genuine,” she explained to the BBC.
Nancy is now facing bankruptcy, and although her case is extreme, the average victim of online dating fraud loses £10,000 according to Action Fraud.
But just as dating app users are at an all-time high, so is the number of people becoming victims of online dating fraud.
If you fall into this category, be especially wary of people that you meet through dating websites.
Online dating can be difficult for women The AARP also says that seniors are a common target of these scams.
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.
