54958433 story Facebook Being Sued Over Mining of Private Messages 170 Posted by Soulskill on Friday January 03, 2014 @01:51PM from the mine-your-own-business dept. Kimomaru writes "Two Facebook users are trying to start a class action lawsuit against Facebook for allegedly mining information from private messages with the intention of selling is to advertisers (full complaint PDF). It's not the first time a social medial player has been in the press over privacy or security issues. But when the services are provided free of charge, does the user have a realistic expectation of privacy or security, especially when it's understood that the user's data is being mined for advertising? If not, should social media networks be allowed to use words like 'private' (as in private messaging) or 'security' to describe their services?"
