We've all had that moment where a friend goes on our Facebook and puts a silly status like "I love c*ck". We've all been there. First thing you do is delete that status so you can save yourself from embarrassment. What you're doing here is protecting yourself and your privacy. We all do it without even knowing. I'm sure you've also deleted someone off your friends list because you feel like they shouldn't know as much information about yourself.
Privacy is a big issue when it comes to social media, and everyone does it, whether they do it willingly, or without even knowing. We all want to protect our personal lives where we can.
