Facebook is facing a class-action lawsuit in Northern California over allegations that the company systematically scans its users’ private messages on the social network without their consent. The lawsuit was originally filed in 2012 and for now, the case is expected to proceed. Facebook claims that the claims relate to historical practices that are entirely lawful, and we look forward to resolving those claims on the merits. Facebook says the company scans the URLs within messages for several purposes like anti-malware protection and industry-standard searches for child pornography.
