Global Survey Group is not really not a survey site. It is a site that is just like USA Survey Panel. At Global Survey Panel you sign up for the site and then are asked to join many other survey sites. Global Survey Panel is a good site to sign up for if you want to join many survey sites in less than 5 minutes.
The information you entered to join Global Survey Panel like name, address, phone, birthday, email, and gender are then sent to all those other sites you choose. It is much quicker to join sites this way, but Insiders In does not recommend joining sites this way. It is much safer to read reviews aout sites and read about the site on their FAQ page. When you do these two things your help prevent yourself from getting into scams.
Insiders In gives Global Survey Group 1/5 stars.
