For porn and disturbing images, Facebook is the new place to be.
Tuesday morning reports began surfacing -- mostly via Twitter -- of Facebook users having pornographic and disturbing pictures show up in their news feed.
ZDnet was the first to report that the images -- involving Photoshopped pornographic pictures and mutilated animal images -- were being spread via a "linkspam virus."
Users were reportedly being duped into clicking on innocuous news feed links and then being fluttered with the images.
"[We are] aware of these reports and we are investigating the issue," a spokeswoman for Facebook told the BBC.
Internet security firm Sophos said the images hit the Palo Alto-based social network about 24 hours ago.
Late Tuesday Facebook said it had discovered what was causing the problem.
