If you want additional amount of money then you'll also need to join more legitimate survey sites and research companies so that you'll receive a daily number of surveys in your email's inbox. If a company requires you to pay in exchange for survey benefits then this is a scam. Signing up for this type of paid survey site or other marketing research group will only get your email address, and sooner or later your inbox will be filled up with a lot of spam.

A valid survey site or marketing research group should know how to respect the decision of survey takers or panel members. They will never try to dissuade them to respond to a survey that requires them to download something from their computer. If you do not want to complete a given survey then you don't need not do so.
