More surveys that disqualify

Lately I feel surveys are not worth doing. The latest survey I did said it would take 9 min. I spent over 10 min and responded to very specific questions. I had to list stores I visited, how much I spent and what I bought for the last week. It then asked the normal age, race, sex, income. I thought the survey was over and I would get 50 SB only to get not everyone can be a winner and 1SB. I feel the survey is getting all the data they want without paying out. This happens several times a week. I keep saying this is the last survey I will do and then I try again. Is this the future of SB surveys. I feel nothing is being done to stop the practice.
