MOTHERBOARD – Oct 12 -The issue has been coming up with alarming frequency for users of Tinder and OkCupid in recent months. Emilio Ferrara, a data science and machine learning professor at Indiana University who studies social networks said the most obvious answer would be that these apps are collecting and sharing your information. Tinder and OkCupid both denied they share user info. Brian Hamachek, a software engineer who has reversed engineered Tinder’s API and is very familiar with Facebook’s API said there is no reason to believe those two sites are comparing your data. He believes the Tinder and Facebook overlap is most likely a side effect of similar algorithms working to connect people.
