He also said that AFACT and other copyright owner groups' requests persistently asked the ISP to cut its customers' services off. Cobden said the volume of AFACT's notifications were akin to spam, and that iiNet had suffered a "constant bombardment" of notifications, which, he said, were unreasonable and burdensome. iiNet's aim yesterday was to establish that AFACT had, since 2007, been attempting to build evidence that proved the ISP had implicitly "authorised" its customers' breach of copyright by not following its orders to either send notification letters or cut off an offending customer's service. Cobden yesterday worked towards reducing the number of alleged breaches of copyright that had been collected by AFACT's two investigators, which were claimed by AFACT's barrister Tony Bannon to have reached 100,000 instances. Cobden told Justice Cowdroy that BitTorrent file-sharing were often pre-configured to be left open for sharing, meaning that many of the alleged breaches were actually single instances.
