A report by AT&T Labs and Worcester Polytechnic Institute said that Facebook and MySpace sent user info to advertisers. When users clicked on ads, the advertisers often knew the users’ names, ages, hometowns and occupations.
“We were recently made aware of one case where if a user takes a specific route on the site, advertisers may see that they clicked on their own profile and then clicked on an ad,” said a Facebook spokesman. “We fixed this case as soon as we heard about it.”
This is another red flag for Facebook, given the company’s ongoing privacy issues.
