This is true! Yesterday, I was playing this flight simulator (check it out! http://web.roblox.com/Dynamic-Flight-Simulator-V-2-04-place?id=75554978) and my friend wanted to join me. While we were talking on Skype, he searched up my profile and saw that I was offline. I was legitly playing the flight simulator game! I even showed my screen! We were both scratching our heads.
