I certainly have done some googling and looking at the website and my sense was that something was up with this company. I did find this [
market-research-pros.integrityconsultants.us] which reflected the same things I was finding. It is extremely hard to get to real information about this company because they buy so many ads, write so many reviews of themselves and obviously have a little army of affiliation linkers out there. My sense is that it is not on the up and up and even if you get paid for your work, there is something rotten here. I was privately talking with a shopper about it and suggested that if they chose to play they open a new email account just to deal with this company, that they link that email address to their PayPal so they got paid and they provide as little personal information as possible. And of course under no circumstances provide any credit card information or banking information beyond the email address for PayPal.
My bet would be that in short order that special email account would begin to fill with sales spam and of course now that you are 'doing business' with them, any phone number you provide will probably be recycled into a pool for making sales calls. So if you choose to play, do so with your eyes wide open.
