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.
Paid surveys easy to come by so don’t worry if you don’t qualify for some of the paid surveys you sign up for. In some cases you might qualify for a survey but after answering a few questions you are removed from the paid survey. This happens sometimes because the answers you have provided have determined that you do not fit into the target group that the paid survey is designed for. Not to worry though, because there are plenty of paid surveys out there that you are eligible for. It typically only takes a few seconds to determine if you are eligible for a paid survey or not so it won’t waste too much of your time.
One nice feature is the ability to shop through Vindale, as they often have offers available through affiliate links. Before buying something new, like an appliance, it is worth signing into their easy to use website and checking if you can get it for less through Vindale. There’s also a popular daily consumer survey paying $1.50 which you can complete every day, for an easy and reliable boost.
You won't get rich doing these things but it's legitimate and you'll get paid in the end. For example, you get a penny for each email you click. You get a penny for a video stream. You can earn dollars for fulfilling offers but those aren't nearly as quick as reading an email. They are upfront in what you get paid so you can decide if it's worth 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.
