Some you’ve heard of, others you haven’t, and one of them will even offer you the opportunity to date a Victoria’s Secret model.

There is often more than one person perpetuating the scam - there have been reports of a room full of people working from the same script.

Often they portray their fictional selves as living overseas or on active duty in the military.

I had a date with one man who, in a flurry of perfectly crafted emails, had seemed so right for me, I even agreed – sight almost unseen – to spend the day with him at Lord’s cricket ground.

I must have been insane (Lesson No 1: never arrange to meet for longer than a coffee). I didn’t find him at all attractive in the flesh – nasal hair, nasal voice banging on about himself and his terrible divorce – and the feeling was clearly mutual.

Lonely hearts still waiting for their soulmate are easy prey for online dating scams.

Many people search for love through online dating sites, dating apps, or social media.

In fact, the figures showed that 3 per cent of Tinder users were between 45 and 54, which meant there were a lot of middle-aged people in its dating pool of 50 million users.

Having been struggling to find a catch in what felt like shallow waters for some time, I decided it was worth a plunge in the depths, however murky.

If you find yourself on the market in your 40s, wading into the app-dating world can feel daunting.
