Are facebook profile spy apps a hoax?

Asked by stars (95) February 6th, 2011 from iPhone

Hi, I’m just wondering if anyone has heard of or had joined a Profile Spy apps? I keep getting requests to join- the claim is that you would be able to know who and how many times one of your friends had looked at your facebook page.
So now I feel weird when I go and looking at pics my friends posts. I don’t want anyone to think I’m spying since that is creepy but I would not even be true!!! I’m not that interested that much in anyone to waste my time actually spying on them!
