Paid internet surveys pose a number of risks, both to the companies that offer them and to the people who complete them. Among the biggest risks of online surveys for businesses is that respondents might lie so that they can do more surveys. Individuals may falsify their demographic information in order to be eligible for additional surveys. They may register with the same company using various email addresses so as to have multiple profiles. A risk for participants is that online surveys are an opportunity for Internet scammers. Another risk of registering on a website for a paid online survey is that the site might give your contact information to spammers. It is therefore always a good idea to register using a different email address than your main one.
