"I downloaded Grindr when I moved to Riyadh for university. I thought I was careful. VPN, fake photos, fake name.
Then the researchers published their paper. They showed how to find anyone's exact location using Grindr. Down to the building. Down to the apartment.
Three weeks later, my father got a phone call.
"Someone had screenshots of my profile. My real face. My exact location. They wanted money, or they'd tell my family, my mosque, my university. In Saudi Arabia, this isn't embarrassment. This is death."
I paid. They wanted more. I paid again. Then I got on a plane and never went back.
Update: Ahmed is now a refugee in Canada. He hasn't spoken to his family in 3 years. Grindr still hasn't fixed the location vulnerability.
