The difference between a scam survey and legal survey site is a lot closer than you think. There are quite a few scam survey sites on the internet, but here are some simple things you can do to tell the difference between them and the legal survey sites.
First of all, paying any sort of fee to join a survey site is not something that you should do. Any legal survey site will never make you pay a membership fee, or any type of charge to become a member. The best and most legitimate survey sites on the web are all absolutely free to join. They will have simple join forms and do not include anything more than your basic profile information and an address to send your check to.
A scam survey site will ask you for everything from your credit card number, to maybe even your social security number. Needless to say, you should never, ever give that information away, unless you really trust the website. Another thing a scam survey site will do is try to make you sign up with a million of their so called "business partners". Nothing worthwhile will come from this. All you will get is an increase in junk mail. Legit survey sites will send newsletters and bonus materials to your email address, but they will never flood your email box with crap, like a scam survey site will do.
Almost every legitimate survey site that I have run across give you easy access to reach their
customer support. The legal survey sites will answer all of your questions, without hesitation, while the scam survey sites will rarely answer your questions. A lot of the scam survey sites do not even have a link to their email address available available and make it very hard to find, because they do not even want you to ask questions.
Just these tips alone should help you in determining which is a legitimate survey site and which is a scam survey site. Some of the differences are subtle, but most of them should be pretty easy to spot. The faster you are able to spot the bad ones, the faster you will be able to find the legal survey site that is right for you to get paid.
