A US mother has made it her mission to track down cheaters and restore justice to the dating world.
Erin Colleen spoke to the Daily Mail about how her flings with less-than-faithful men inspired her to help others from going through the same heartbreak.
So Colleen took to the dark, damp and dirty corners of the online dating world to unearth the Tinder-trawling cheats.

"I can't stand cheaters. I was cheated on. It was devastating... nobody ever said anything to me about it," she told the publication.
With a background in data mining, Tinder's Superwoman is able to locate the partners of married men searching for a mistress on the popular app.
"Whenever I see a profile that says 'married' or 'looking for something discreet' I immediately swipe right to see if I can out the guy," Colleen explained.
She has now reportedly exposed five men and their adultery.
"I do this to protect other women. I don't want any other woman to go through what I went through," she says.
Colleen says the men's partners have always been grateful for her dating detective work. Some wives have admitted they were suspicious all along.
Colleen has a stern warning for swiping sneaks.
"If you want to cheat, you better expect it to get back to your partner," she says.
"It's 2019 now and cheaters can't hide anymore."
