AFACT can stop abusing the legal system and fuck off. They have a procedure that allows them to inform an ISP of an infringement via a magistrate, the ISP will happily comply with the request and send the agreed details to the respective law enforcement agency. The fact that AFACT have sent 0 of these requests since they were introduced almost 10 years ago proves they really don't give a shit about the ISP, or due process.
An ISP is NOT a judicial body. Infringement Notices are not legal documents and AFACT is not Law Enforcement.
