Facebook, Others Giving User Private Data To Advertisers
superapecommando sends along a Wall Street Journal report that indicates that Facebook's privacy troubles may be just beginning. "Facebook, MySpace, and several other social networking sites have been sending data to advertising companies that could be used to find consumers' names and other personal details, despite promises they don't share such information without consent. The practice, which most of the companies defended, sends user names or ID numbers tied to personal profiles being viewed when users click on ads. After questions were raised by The Wall Street Journal, Facebook and MySpace moved to make changes. By Thursday morning Facebook had rewritten some of the offending computer code. ... Several large advertising companies ... including Google Inc.'s DoubleClick and Yahoo Inc.'s Right Media, said they were unaware of the data being sent to them from the social networking sites, and said they haven't made use of it. ... The sites may have been breaching their own privacy policies as well as industry standards. ... Those policies have been put forward by advertising and Internet companies in arguments against the need for government regulation."
My reading of the WSJ article is that the sites were (perhaps inevitably) passing a referrer URL along when the user clicked the ad. This URL is, naturally, one of the user's pages, and will explicitly or implicitly identify the user. The advertiser can then identify the user's page on the social networking site and retrieve any public information there. The WSJ makes it clear that the information is not passed on directly, which goes some way to explaining why the advertisers claim never to have used it.
No kidding!!! What do you say at this point?
Yes I'm sure
No. That's impossible.
Are you vetting every photo any of your friends or family has every taken? Monitoring their online activies? Are you vetting all photos taken by other people at, say, social events (weddings, etc)? Are you vetting their online activities? No? Then you can *never* be sure if someone isn't posting information about you, somewhere. Well, unless you just hide in a basement with no friends or family to speak of, in which case privacy is the least of your problems.
