In an act that can only be described as the biggest show of girl code ever, an absolute hero has gone on a one woman mission to expose cheats and report back to their wives and partners.
Erin Colleen, 34, says she has been cheated on several times over the years, so wanted to stop other women staying in the dark while their partners arrange hook-ups online.
So, in a bid to protect other women from wasting their time with awful people, she went full detective and decided to use skills she'd learned in her career as a data miner to track down men's partners and mums - and expose them.
She's successfully outed five men so far and, unsurprisingly, each woman has been thankful, although obviously upset. Erin's even received d*** pics and reported them back to their partners.
During one chat, Erin received x-rated pictures and videos, and when she exposed him to his girlfriend, both women plotted how to get more evidence from the shameless sleaze.
When one woman learned the truth about her fella, she text Erin: "I really wish there were more people like you in the world.
"I'm a nurse who worked 80 hours last week so we could go to Disneyland. Kind of ironic working to go to the most magical place on earth when something like this was going on back at home."
Erin, from Washington DC, US, has now made it her mission to expose as many cheats as possible - to ensure no other women go through what she has.
She said: "I can't stand cheaters. I was cheated on [in the past].
"It was devastating to learn he'd been doing it right under my nose for years, and that nobody ever said anything to me about it.
"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.
"I do this to protect other women. I don't want any other woman to go through what I went through.
"Women are starting to really look out for other women, even ones we don't know, so if you want to cheat you had better expect it to get back to your partner.
"It's 2019 now and cheaters can't hide any more."
Last weekend, Erin outed two more men to their partners after chatting with them over Facebook and Snapchat for a number of months.
Erin said: "[The man's wife] said he was defending himself saying that I was trying to ruin his life and it wasn't true. I see right through the men's excuses. [An ex] used to say that he was unfaithful because he was lonely. I used to feel bad for him.
"It turns out he was unfaithful long before our [relationship] had issues. These men are manipulators. They expect free emotional labour from women, especially their partners, but they still want to be able to fool around with whomever they want."
Better watch yourselves out there, Tinder cheaters.
