Stalking someone in Facebook?

These types of applications are fake. They don't provide accurate information. I have got the following text from Facebook Security group. "Facebook Security:- On Facebook, there's no way to see who has visited your profile. We've also prevented others from providing this functionality. We're working hard to block and remove websites, Pages, and applications that claim to do this. If you see one, don't be fooled, and report it to us immediately." You can join this group by searching for Facebook security and join the group with the shield on it. So really my advice would be don't download it. It will be just a waste of time.
