Don't even bother with that one. It's not a survey, but (apparently) work that a human can do quicker than a computer. It generally involves going through websites and confirming or extracting some data. Takes ages, and like you say, for very little reward. Does make you wonder who is actually wanting this information and what it's being used for.
Samplicio seem another that is a waste of time; when I clock on it it ALWAYS say there are no surveys available. The only ones of any use are the Ampario surveys, one for 150 credits and the other for 450 credits.
