They include sites that seem to be their competitors because they earn referral fees when you buy memberships. A couple mentioned in scam forums even try to dupe you into buying the same list at other membership sites they own under different names. Naturally, these sites also have an incentive to exaggerate how much you'll earn from online paid surveys.
I also have used Synovate Global Opinion Panels, which is now I-Say by Ipsos. They send you surveys pretty frequently and the points you accumulate can turn into actual money! You can receive an actual check from them, or choose to redeem for a gift card. I haven’t cashed out with them since they changed into the new system, just because I’ve really stopped taking the surveys because I’m lazy 🙂 Here’s the link: http://i-say.com/Rewards/RewardsProgram/tabid/203/language/en-US/Default.aspx
Swagbucks: The best part of this site is how easy it is to cash out. Save up your points if you want, or redeem for a $1, $3 or $5 Amazon Gift Card right away! Get paid $0.50 to $50 per survey, depending on how long it takes you, plus a $3 bonus for signing up. Swagbucks will also pay you to watch videos, try products, shop online, and even search the web. Go here to sign up.
The number one reason why I liked MySurvey the best out of the 30-something sites I had the privilege or misfortune to try, was no doubt its versatility. This versatility is present not only in the reward system and the referral program – which are important aspects on their own – but clearly shows in their surveys too. Filling out boring surveys always feels like hard work, even though it’s really not if you think about it. With MySurvey, you will see a huge variety of different topics.
By only sending you questionnaires you are already qualified for, Pinecone wastes far less of your time than many sites which require you to fill our qualifying questions before starting each survey. However some users have said they don’t receive very many surveys, which could be a consequence of their careful filtering. Equally the site retains the right to remove you from their panel if you no longer fit their desired demographic, so make the most of your membership while you have it!
It’s a very well-known scam. You cash the check, then they ask you to either wire some of that money back to them as some sort of fee or buy something for them and send the item to them. So, you deposit the check, then wire some cash to them thinking that the check you just deposited will cover that. A few days later, after you already send them the money, the check will bounce and the money you send to them will come out of your own account.
