silentbrad writes "The CBC (among others) reports: "A Facebook spokesperson is denying reports that private messages sent by users on the social networking site have become public. The purported glitch began generating attention Monday after French newspaper Metro reported that private messages dating from 2007 to 2009 had become accessible to friends and acquaintances on their profile pages. Other newspapers across the country began reporting similar incidences, citing reports from the site's users. The issue may be related to Facebook moving to its Timeline layout worldwide.
... The company issued a statement in response, saying: "A small number of users raised concerns after what they believed to be private messages appeared on their timeline. Our engineers investigated these reports and found that the messages were older wall posts that had always been visible on the users' profile pages. Facebook is satisfied that there has been no breach of user privacy." TechCrunch.com wrote that there was no evidence the messages in question had been private, and posted an explanation from a company spokesperson. "Every report we’ve seen, we’ve gone back and checked. We haven’t seen one report that’s been confirmed [of a private message being exposed]. A lot of the confusion is because before 2009 there were no likes and no comments on wall posts. People went back and forth with wall posts instead of having a conversation [in the comments of single wall post.]“"
