WSJ - Oct 12 - A study shows that 45% of the top 185 U.S. websites transmit identifying details about their visitors to at least four outside websites. The data transmitted was primarily a “username”. OKCupid sent the gender, age, zip code, relationship status and ‘drug use frequency’ to two companies that sell personal data in auctions, BlueKai and Lotame. Lotame confirmed that it has a data licensing relationship with OKCupid, but said it does not use data in the “drug use category.” BlueKai said that it does not buy or sell data attributes like “drug use frequency” from OKCupid.
