For a second, I considered sending in FB evidence too. I got a new phone on June 15th and I posted a mobile upload of myself that automatically used GPS and identified my location in my post. I figured I wouldn't send it in because I had other, more traditional evidence, but it's nice to know that it's not out of the question to take advantage of Facebook's invasive nature.
