Online dating apps are big business in the UK but there is still one very real problem preventing developers from real and sustainable growth: users can't be 100pc sure that the person they are talking to is the person that they say they are.

Online dating is nothing new, and while some straight people might hesitate to post their personals on the internet for fear of stigma, almost every lesbian I know has at some point gone online to find lurve or at least sex.Ok Cupid has more features, filters, and functions than any other dating app I’ve scene. Compatibility questions that allow you to see your “match %” with other users b.fun quizzes galore so other people can pre-judge you c.One 24-year-old man from Stockwell, London, who used to infiltrate online lesbian apps posing as a lesbian, said he did it simply to amuse himself. “But when I was bored I used to go on these chat sites for kicks.” Ruth Hunt, deputy chief executive at Stonewall, a gay, lesbian and bi-sexual charity, says this is no laughing matter.“This issue of men lying to meet lesbians is as old as time, they’ve just found a new way to do it," she says."While we can’t say for certain what is motivating this behaviour, we would advise caution when using the internet to meet partners and recommend that people always try to meet in a public place.” What is clear is that there is a huge potential user base for lesbian dating apps and they could come to represent quite an attractive commercial advertising proposition.
