When a young woman in Denver met up with a smiling cardiologist she matched with on the dating app Hinge, she had no way of knowing that the company behind the app had already received reports from two other women who had accused him of rape.

She met the 34-year-old doctor with green eyes and thinning hair at Highland Tap & Burger, a sports bar in a trendy neighborhood. It went well enough that she accepted an invitation to go back to his apartment. As she emerged from his bathroom, he handed her a tequila soda.

What transpired over the next 24 hours, according to court testimony, reads like every person’s dating app nightmare.

After sipping the drink, the woman started to lose control. Her memory blurred. She fell to the ground, and the man started to film her. He put her in a headlock, kissing her forehead; she struggled to free herself but managed to grab her things and leave. He followed her out the door, holding her shoes and trying to force her back inside, but she was able to call an Uber, vomiting in the car on the way home.

She woke up at home, soaking wet on her bathroom floor, the key to her house still in her door. She continued vomiting for hours. When she came to, she reported the assault to Hinge.

Hinge is one of more than a dozen dating apps owned by Match Group. The $8.5bn global conglomerate also owns brands like Tinder (the world’s most popular dating app), OKCupid and Plenty of Fish. Match Group controls half of the world’s online dating market, operates in 190 countries and facilitates meetups for millions of people.

Match Group’s official safety policy states that when a user is reported for assault, “all accounts found that are associated with that user will be banned from our platforms”.

So why, on the night of 25 January 2023, was Stephen Matthews still on the app? Just four days before, Match Group had been alerted when another woman reported him for rape. A little more than a week later, he was reported for rape again. This time, the survivor went to the police.

None of these women knew that the company had known about his violent behavior for years. He was first reported on 28 September 2020. By then, Match Group’s safety policy was already in place.

Even after a police report, it took nearly two months for Matthews to be arrested – the only thing that got him off the apps. At least 15 women would eventually report that Matthews had raped or drugged them. Nearly every one of them had met him on dating apps run by Match Group.

On 25 October, a Denver judge sentenced Matthews to 158 years to life in prison after a jury convicted him of 35 counts related to drugging and sexually assaulting eight women, drugging two women and assaulting one more for a total of 11 women. Attorneys for the women said much of that violence could have been prevented.

“It is shocking that for years after receiving reports of sexual assault, Hinge continued to allow Stephen Matthews access to its platforms and actively facilitated his abuse,” said Laura Wolf, the attorney representing the woman whose police report led to the arrest. Following best practices for reporting on sexual assault, the Dating Apps Reporting Project is honoring survivors’ requests for anonymity. Matthews’s attorney, Douglas Cohen, declined to comment. A letter that the Dating Apps Reporting Project sent directly to Matthews in jail went unanswered.
