Does not work. I tried three accounts with the Facebook name and the url. Nothing, just: “Error! We could not get all the details about the page properly.” Tried well known company Telia: “This report was recently generated by the system and history data is minimal at the moment.” Blank page! Telenor gave: “Error! We could not get all the details about the page properly.” I will do better manually in a few secs!
This is a strange web app. One could almost think that its aim is collecting info, not finding!
