While there are a lot of reputable survey sites on the web, there are also a lot of not-so-reputable sites. Avoid any survey site that:
Requires you to pay a membership fee
Guarantees you a set income
Does not make clear how you'll be rewarded for your participation
Asks for too much personal information ¡V you shouldn't have to give out your Social Security Number, credit card number or your bank account information
