Prizerebel is a GPT(Get Paid To) site. You complete offers and surveys to recive points. The surveys and offers are provided from other individual companies who make deals with Prizerebel. Basically Prizerebel agrees to provide a company with users to cpmplete their offers and surveys. When a user successfully completes one of those offers or surveys the company gives Prizerebel a certain amount of money. Prizerebel then gives a percentage of that money to the user who completed that offer in the form of points. These points that you earn can then be traded in for prizes from Prizerebel. So why do the companies want you to complete offers and surveys? Well the surveys give them information on people's preferences and general lifestyles. The offers also provide somewhat of an advertising oppurtunity.
No, it is not. It is really hard to prove, because so many people think that if something is too good to be true, then it is a scam. The thing is, that really the Free NX isn't just given to you like that, your actually earning it. As explained above, Prizerebel does get profit from this so why would they scam you? The site has over 20,000 forum users and if all that info isn't enough, there is also a testimonial page.
