Is Paid Survey Scams?

If you ask me this question, here is my answer. From my experience a lot of online paid survey company or website were scams. I have joined 30 paid survey company before and it all scams. Many people was tricked to believe that these paid survey opportunities are genuine. They offer surveys from large international company like Coca cola but in reality there are no such surveys except for some people who live in United States only. The $5 to $30 per survey, they claim, will be given to you once you have registered as a member (of course you need to pay to be a registered member) then they grant access to their company database to fill out online surveys. Unfortunately, two or three weeks later there was no survey comes to your personal inbox. After you ask for refund, the admin was gone. You can't contact emails that they give to you.
