NPR - Oct 1 - Ashkan Soltani, a digital privacy specialist, set up a fake account at OkCupid.com to demonstrate how private companies are tracking what people are doing online. OKCupid's questionnaire asks him for a wide range of information, including drug use. While at OKCupid, he launches two softwares — Collusion and MITM Proxy. The Collusion program reveals that ~50 companies are tracking Soltani's computer as he visits OKCupid. Some are advertising firms, while others collect information and then sell it to ad firms or industry research companies. MITM Proxy shows information that those companies are receiving from OKCupid. Nothing unusual. Websites commonly allow other companies to monitor what users are doing on their sites but at least one company, Lotame, learned that Soltani uses drugs "often."
