We know: Despite its best attempts at proving otherwise, Facebook and privacy have an oil/water reputation -- the latest legal news regarding the company won't help that any, either. A California judge recently ruled that The Social Network will face a class-action lawsuit following accusations that it peeked at users' private messages without consent to deliver targeted advertising. Facebook tried to dismiss the claims, saying that it didn't break any laws and that the alleged message scans were protected under an exception in the Electronic Communications Privacy Act, according to Reuters. Which one specifically? That these "interceptions" are lawful if they occur over the "ordinary course" of a service provider's business. The presiding judge countered, saying that Zuckerberg and Co. failed to offer explanation of how the scans fell under the website's ordinary course of business.
