If you were angry with Facebook’s self serving and financially motivated user policies this would outrage you. WSJ ( Wall Street Journal) reported that  Facebook along with MySpace, Digg, and a few other  social-networking sites sent advertisers information (user names, ages, hometowns and occupations) about  which specific users were clicking on ads, based on a report at AT&T Labs and Worcester Polytechnic Institute.

The AT&T Labs and Worcester Polytechnic Institute’s report was published last August, but Facebook only changed its code to stop sending the information after the WSJ contacted the company for today’s story.

“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,” a Facebook spokesman told the WSJ.

Several large advertising companies were identified as receiving the data, including Google’s DoubleClick and Yahoo’s Right Media, but they said that they were unaware of the data being sent to them from the social-networking sites, and said they haven’t made use of it.
