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.
CashCrate is a great site pairing traditional surveys with a range of unique deals that can help you make money online. After signing up with a few details and filling in a brief survey for your profile, so CashCrate can identify some basic demographics, you’ll be awarded your first 25 cents and be on your way to greater riches! The best deals and offers are available for US users, and the minimum earnings to have a payout from CashCrate is $20 – which they pay you and their six million users as cash.
What I like about them is they also run focus groups in the San Diego area. I signed up to receive phone calls and get them. I have little ones at home so it doesn’t quite work out for me to attend right now, but they do pay well. They were looking for adult men once to attend a focus group about food, and I shared the info with a friend’s husband who was out of work and made $80 in 2 hours with them at the focus group.
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.
