I just came from Facebookspy.net and I found if you spend $1.99/month they will help you to track your desired friends acitivies on facebook or simple you can paste the ID of any facebook user and they will do the rest of works and gethering his/her information and show to you. Sometimes it’s importent to hide some messages from facebook mini feeds or newsfeed. But, Facebookspy can tack all of your hidden activites and also they will show your messages with time(I am not sure about this apps). If it’s true it can break anybody’s privacy. What do you think?
