Are you a match? From an NPR piece on surveillance, corporations and the government absorbing data from dating sites in order to reveal the real you:
Examples from the series include online dating sites, like OKCupid.com. The report shows how profile questions on the site about things like drug use, religious beliefs and more were transmitted to a data tracking company, along with the user’s IP address.
When you log in with a username and password to sites like Gmail, Amazon or OKCupid, your behavior can be linked to your real name or email address. Software privacy specialist Ashkan Soltani said personally identifying information also can unintentionally “leak” to third parties, even if companies say they have no need for such data; it’s not clear what happens to the information once it falls into their hands.
