The phrase "bypass survey" refers to the act of bypassing a survey that is forced on the user before allowing him access to premium content on a website. This can be done through the use of survey bypassing software, such as XJZ Survey Remover.
Certain websites exploit the visitors by requiring them to fill out surveys, whereby websites are able to acquire their personal information in addition to profiting off them. Survey bypassing software prevents the survey from initiating and immediately allows access to content that was previously blocked. XJZ Survey Remover cannot trick the server into thinking that the survey has been completed, because there is no way to download the file that verifies its completion.
