I worked this just long enough to get five surveys in, so 1000 points plus the pittance (50-75) per completed survey. I think I was at a 20% completed to disqualified ratio, so it took a few wasted days while listening to nice music.

But the ones I got disqualified for (sometimes after an investment of 5-6 minutes) paid off at the huge rate of 3 points per failed survey. Fooey on these bozos.
