Not that you would be naive enough to be taken in by this but just to be safe I am posting this warning here.
You can read more about this on the link below. There are some good reasons to suspect that it's a fraud and the same points you should keep in mind any time you come across a website that looks like a real great opportunity.
In the same article you'd see a screenshot from the mixreq.com saying, you get paid $4 for doing a survey and you can do the same survey 3 times a day. That made me laugh. No legitimate data-collector would let you take a survey more than once. Once you fill the form, second time around you will either enter the same data or untrue data, both are useless for statistical analysis.
So, beware. Please be careful on the internet. Not everybody is as honest and truthful as you are, tread with caution!
