I have never had the pop up that you are describing. However, on another gpt site, my quality rating on one of the survey panels dropped way down. I could not understand why so I sent a support ticket to the survey company.
I was informed that I had taken a survey or surveys that were later reversed or revoked. That was why my score dropped.
The strange thing is that my earnings were never affected. I was still able to cash out when my balance reached a required amount. My cash out was never affected and I have a check in my home as I speak.
So I have no idea what in the world is going on with some of these survey platforms. I, too, am getting a little tired of the survey scene.
