The concept of data mining and profiting off that data mining isn't anything new.  And while some companies engage in some rather disreputable practices to do this, Global Test Market seems to be doing just fine with the whole “consent to disclose” thing.  More importantly, in some cases this may help you as some companies will offer to do more specialized product testing once they've identified you as their target demographic.

Cashback shopping: Who doesn’t love getting cash back? It's a great incentive for shopping because it feels like you're being paid to do so. It's usually best to use the offers only when you were already intending to buy the product. If you love saving money at discount stores or at places that offer cash back, there are a lot of survey sites out there that will open a lot more offers to you. Survey sites can offer cash back because they're paid a portion of the profit for referring you.
i belong to onlycash, mommytalk, talkbacksurveys There was a fourth one I joined ….called watch and tell, or something similar…….(they originally had another name) …Somehow I deleted the site, …and cannot find it when searching for it. It was related to the first sites I named. ….I was ready to cash out, …and cannot find it. Anyone know the name?????
I reside in Jamaica. I am at a disadvantage in securing paid surveys because of my location as the so-called first world countries receive all the choice survey sites leaving the crumbs that fall from the Master’s table. The survey field needs to be leveled. Because of the advent of IT capability, the world is just one community. Everyone is aware of what goes on everywhere.
Harris Poll has made a strong presence in the market research industry. They are a member of the National Council of Public Polls (NCPP), the Council of American Survey Research Organizations (CASRO), the Council for Marketing and Opinion Research (CMOR), and the European Society for Opinion & Marketing Research (ESOMAR). The firm abides by the  standards of these organizations, thus proving their reputability.
They are new to me. I did a search and wasn’t able to turn up much online, other than this – https://forum.surveypolice.com/index.php?/topic/4110-saw-an-advertisement-for-iglobalsurveys/. Someone thinks they are more of a “survey router,” not the same as answering Q’s directly for a survey panel. So I think I personally wouldn’t sign up, but as always I recommend that you do you your own research in addition to the research I’ve done.
