I finally found out why I am not receiving surveys from this site, they claim I (or someone else) is trying to sign in from another country! OK, I can believe that, it has happened to me with another survey site. Must be a problem with my ISP who sometimes shows up as being in the Cocos Islands for some reason, instead of Sydney. At least the other survey site notifies me of the problem, this site just de-activated my account, no notification, nothing. Now they have re-activated my account the the 2nd survey I did was for about 15 minutes and 100 points, but as soon as the survey was finished I was informed that my session had timed out. No points.
Must cancel this site and stop wasting my time.
