Terrible site. Poorly designed surveys, you will get many pages in and much wastes time to be informed that "you don't qualify for this survey". Also, credit is not given for some completed surveys. Finally, multiple surveys get you to a point where the survey doesn't take input or is otherwise unresponsive and all time is wasted. I don't believe the site is a scam, but don't bother with it unless you have tons of time and expect nothing for it.
