Graduated response (also known as three strikes) is a process that copyright owners have negotiated with ISPs, sometimes with legislative backing, to involve ISPs in copyright enforcement. Typically ISPs are required to give two warnings to users whom the copyright owners allege are infringing copyright, then after a third alleged infringement to terminate or suspend the user’s Internet connection. Under an agreement reached between copyright owners and ISPs in the United States in 2011, users will receive six warnings before any punitive action is taken by ISPs.
