Facebook is Going Above and Beyond to Let Users Help Those in Trouble
From the Huffington Post:
If a Facebook friend posts something that you feel indicates he or she could be thinking about self harm, you'll be able to click the little arrow at the top right of the post and click "Report Post." There, you'll be given the options to contact the friend who made the post, contact another friend for support or contact a suicide helpline, the University of Washington reported on Wednesday.
After that, Facebook will look at the post. If Facebook feels like the post indicates distress, it will contact the person who posted it. That person will be greeted with the following pop ups when he or she next logs in.
