Revoke payments for surveys are a thing if the survey company thinks you weren't truthful with what you were putting down for answers in your surveys they have every right revoke it. Also if you take a survey to fast that can get a survey revoked down the line to because trust me they do check how long you take to do that stuff
I have been doing surveys for many, many years with different companies I know how the system works. I have also done many many surveys here on Fusion Cash otherwise I would not have made the amount of money I have here if I had not. My frustration came when Fusion cash started revoking payments only when I started to get close to cashing out. Fusion cash also does not give an exact answer to why the payment was revoked which makes me question. I have completed 3,546 surveys with Ipoll.com over the years I have never had a payment get revoked with Ipoll.com.
