Josh Halliday, The Guardian:

Facebook has been accused of deceiving developers after it emerged that the social networking site did nothing to verify the security of applications it was paid tens of thousands of dollars to review, and which it assured users had been checked.

Basically, Facebook offered a “verified” program to developers for a fee. Apps in this program would receive a checkmark of approval with the promise to increase discoverability for users. It turns out that Facebook pocketed the money and didn’t check anything.
