We have been receiving several complaints over time stating that our Facebook Invisible Detector is not displaying the result users are waiting for. All we can say is that you can keep on using our service, as we can assure you that our Facebook Invisible Detector working perfectly. In the matter of fact this is the only such service that only needs an ID for detection.
Most likely users came across an exception and they didn’t read the description on our Facebook Detector page, where everything is explained that a visitor needs to know in order to successfully use our Facebook Invisible Detect service.
The exception mentioned above is none other than the private Facebook profile. If someone is checking an ID, that has a profile but the owner has selected that the profile to be private, than the detector isn’t able to see it as no one can who is not logged in and in the person’s friend list.
You can very easily check whether a Facebook profile is set on private or not. All you have to do is to simply copy the profile’s URL, and paste it into another browser where you are not logged in (into Facebook obviously). If you will receive an error message, than it means that the user has set the profile on private.
