Google has admitted to accessing private data on Facebook users to augment AdWords, thereby breaking Facebook's terms of service, according to AllFacebook.

The slip-up occurred amidst Google's relationship with Facebook application developers. Google sells advertising to developers and allows app-creators to redirect info from user profiles through its AdSense network.

In a statement, Google claims it has since fixed the issue. The mishap has been positioned as a mere data glitch.

Facebook itself has met resistance in how best to connect its piles of reliable user data with advertisers.

Last week, it announced its Social Ads system that turns users into brand endorsers. But since the new ad program uses members to push brands without their written consent, it essentially breaks New York law in the process.
