Facebook is drawing fire from privacy activists after unveiling a new policy that could turn users' data and pictures into advertising.
The new plan would "dramatically expand the use of personal information for advertising purposes," said a letter this week to the US Federal Trade Commission by six privacy organisations.
The letter said the changes violate a 2011 consent order with the US watchdog agency and urged the FTC to "act to enforce its order."
If the changes take effect, the letter said, "Facebook users who reasonably believed that their images and content would not be used for commercial purposes without their consent will now find their pictures showing up on the pages of their friends endorsing the products of Facebook's advertisers."
"Remarkably, their images could even be used by Facebook to endorse products that the user does not like or even use," added the letter from the Electronic Privacy Information Center, Center for Digital Democracy, Consumer Watchdog and three other groups.
Facebook unveiled the changes as part of a settlement of a class action suit over the use of user names and images in so-called "sponsored stories."
According to the letter, Facebook's existing policy allows its users to limit how their name and profile picture may be associated with advertising.
Under the newly proposed policy, Facebook says, "You give us permission to use your name, profile picture, content, and information in connection with commercial, sponsored, or related content."
Activists say this allowed Facebook to turn virtually all user data into advertising.
"Facebook has long played fast and loose with users' data and relied on complex privacy settings to confuse its users, but these proposed changes go well beyond that," said John Simpson, Consumer Watchdog's privacy director.
Also endorsing the letter were the Privacy Rights Clearinghouse, US PIRG and Patient Privacy Rights.
Facebook officials point out that its policies haven't changed, but have been clarified under the new language.
