There have been several complaints that came to us via our support page, in which users have stated that our Invisible Facebook Detector didn’t return the results they have expected. We encourage people to keep on using our Facebook Detector service, as it is working 100%. In fact it is the only Facebook Detector online that is capable of detecting profiles only after the ID.
The issue that our users might have come across is most probably an exception that is stated on the Facebook Detector page. Please read carefully the description under each detector, as there all information is shared with you that is necessary for a user to know in order to complete a successful detection.
This exception that we are talking about is one regarding the private profiles that Facebook users being verified they might have. If someone has entered an ID with which a profile has been created, but the owner has selected the profile to be private, our detector can’t see it, exactly as you can’t see the respective profile when you are logged out or if the profile is not in your friends list.
In order to check, whether the Facebook Profile is private or not, you can simply log out of your account, and then type in the browser the profile’s URL. If you will get an error message that means that the profile is private.
