There are users who are writing on the support page that the detector is having some problems or that it gives back on rare ocasions false results. First of all, it is recommended to read how the Yahoo detector is working. There are only limited cases, which occur extremely rarely, when the detector doesn’t work properly.
I find it amusing when I see and know that all detectors are working on the exact same principles and exploit the same vulnerabilities of Yahoo servers, and even so, many reach out to affiliate programs of large detectors, they rapidly create a website and simply start spamming blogs that their detector is the best working one. I know that Imvisible offers a high quality affiliate program and also it is free, but I am really amused when I see the competition with huge yahoo detector working 100% ads, but they have the exact same limitation as others, granted they are few, but they still have it. These are the ones who believe that if they don’t create a contact page, if they don’t answer to people, they are perfect and their second hand websites are the best.
Yes, under these circumstances we can say it out loud IMvisible is working 100% correct.
