Yes I am totally agree with you, iam also gives my original info to these sites, then also they disqualified in so many surveys, they are not pays us they only gathering our personal data,You can be right but to some extent I'll have to disagree with you even you all this most of the time they still get to disqualify you or make you miss the survey, to me survey doesn't pay at all it's just there for site recognition
some times I think they are sells our personal data to others.
