In a private tracker, I assume there are no narcs. If there was one they’d have to get a list of IP addresses for their intellectual property, then track down dozens of different ISPs to send them notices. If get a notice, I will delete the media, my account, etc. In court, the only proof they have is that my IP downloaded content. I will show them my public unprotected guest network, letting them know it was probably one of my neighbors. Unless they can find a copy, there’s not much more they can do. This is not legal advice. For actual legal advice see EFF.org.
