Hello, I decided to put myself into downloader's position and see what steps have to be taken by the person downloading the file to complete the survey and unlock it. I tried mainly Cleanfiles but also Sharecash and CPAGrip. Despite trying multiple times, different offers, different countries, proxies, online phone numbers, fake data, etc. I was unable to unlock even a single file. Most of the times there was a neverending chain of surveys, none of which seemed to unlock the file. Why is that? Are CPAs companies simply becoming scam? And how they even ensure that a survey was completed? By cookies or some other means?
