"In an effort to thwart online users who casually download films, music, and other media content illegally, ISPs under six-strikes policy will use a series of escalating messages to warn customers that they have been tracked. Downloaders of allegedly copyrighted content will be forced to acknowledge they have received warnings by either checking boxes or watching educational videos about piracy, depending on the relevant ISP."
