Graboid Video is basically a paid file sharing service, it only searches the Usenet for uploaded videos, most of which is copyrighted and not legal to download. Even if you pay for graboid, you are only paying the software developers and not the film makers. In essence you are paying a monthly premium to engage in illegal practices.
