It has been few days, I am seeing many of my friends applications, that are claiming to show who has viewed your profiles along with the statistics how many times they have visited it. Also few facebook apps says that, there are total this much of views out which this much is visited by male and female. All such applications are fake and they have been spamming.
According to the official FAQ of facebook.com, it clearly states that facebook does allow any such information to any application. If any application claims it, will be banned if report it to facebook.
