She could have just deleted her profile
Unless I don’t understand what this means (I don’t Facebook), why on earth would she do that?
Many people feel facebook is addictive and takes up too much time so they delete their profile to stop themselves from using it. But seeing as the entire profile can be brought back in a few clicks, any attack against your usage of facebook would be a useless venture, no matter what technical data you’ve obtained.
I have no idea what you are trying to say. She blocked him from viewing her page. What makes you think she’s addicted to Facebook and wants to get away from it?
