I recently signed up for a couple of PPD sites, and tested them to see how it went. Well, because I am not in the US or from any of the other survey/download regions, and of course I don't want to "click on my own ads" so to speak, so I paid some people on Fiverr to test the links out. Well, I found that the file that was locked was only available once out of maybe 4 - 5 attempts per Fiverr gig. It seems the person filled out the survey or whatever and didn't get the file unlocked. I thought oh, it must be something they are doing wrong. So I said, ok, I am going to have to do this myself via a VPN. I tried it as well, and the same thing was happening to me. I DL'ed some games or whatever in order to unlock the file, and not ONCE did it give me access to the locked file, even though it said "thanks for completing the offer" via a new page. Have you guys experienced something like this before, or am I the most unluckiest person on the face of this world? Thanks in advance.
