I just got 4 surveys this morning when I got up, it was crazy!
At least 2 of them were location based ones. They seemed like they were almost test questions ("which of these stores have you been to in the last 3 days?") just to see if I was lying or something.
I just started using this a week ago and all of my surveys have been 'Where were you?' They must be testing location services or seeing if I am real.
