Scammers use a diverse variety of methods to allure and dupe unsuspecting victims. Some ads and offers look so real that even the most seasoned internet veterans can be tricked. However, many scams target people new to the market who may be more susceptible to “get rich quick” schemes because they're unaware of what you can reasonably make taking surveys. It is incredibly uncommon to be offered more than $10 to complete a 20 minute survey. Not that one offering that or more is definitely a scam, it's just important to be cautious. While some experienced and well credited survey takers receive legitimate offers paying that pay big money, if you're new to survey taking you should definitely steer clear of anyone offering you hundreds to complete a survey.
Instagc is by far my favorite site. There are tons of surveys, email sign ups, free sample offers, videos, etc. Once you earned enough (usually about $5) you can redeem for gift cards INSTANTLY. They also have pay pal and direct deposit. As a stay at home mom with a tight income, Instagc has been a godsend. It’s free to join, of course.

Something unique that MyPoints offers that most other similar companies don't offer is the ability to earn cash back on some in-store purchases at select stores, along with their online paid surveys. Also, although their online store cashback rates aren't the highest in the industry (ironically, Swagbucks beats them on several offers), they do have special offers that other companies don't have, such as a bonus to sign up for Amazon Prime.
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.
IOCS is a not-for-profit research organization that conducts studies and experiments on shopping-related behavior – things like how we, as consumers, evaluate products, how we make the buying decisions, etc. Although the focus is mostly on shopping related behavior, some of their experiments and studies include broader areas of marketing, psychology, and economics.
