Survey Junkie makes it quick and easy to jump into the survey game. According to their websites, they say they are the “most popular spot online to earn cash and rewards for sharing your thoughts,” while that might not be technically true, they are one of the largest survey sites out there. They were launched all the way back in 2005 (which is pretty old for a survey site) and they have over 4,000,000 members.
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.
Something very important to note before signing up at any site claiming to pay you cash to take surveys is that all legitimate sites offering online surveys that pay do not charge registration fees – they are free to join. Some sites may even offer you bonus as you sign in, to show you they are happy you have become a part of their team and helping them increase their revenue.
Ipsos is a funny name for one of the oldest and largest global market research companies. They were founded in 1975 and if you follow US politics, you'll recognize them partnering often with Reuters to produce approval surveys of Congress, the President, and other notable figures. They're headquartered in Paris, France and publicly traded on the Paris Stock Exchange. They have revenues of over a billion dollars – Ipsos i-Say is just a small piece of their business.
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.
