I’ve Had a Cyberstalker Since I Was 12 (2016)
If anyone from Facebook is reading this and wants to help, ALLOW USERS TO HIDE PRESENCE.As-is, any time you log into Facebook, anyone who is friends with you can see that you are active in the Messenger bar on the right-hand side (even if you have chat disabled).  This gives stalkers (who, as the article explains, are sometimes best not blocked) an excuse to message you, to which a victim will feel pressured to respond.  This makes Facebook a very unpleasant place to be.I personally have written a Chrome extension to hide my presence.  Facebook, please ALLOW USERS TO HIDE PRESENCE if you want to make a positive impact against stalking.
