I'm well aware of how trackers and torrents work. But again, do you think law enforcement understands the nuance of that?
Also the government and private companies have argued in the past that the hashes and lists of peers is inducement and enablement for copyright infringement.
So do torrent websites like the pirate bay. That doesn't protect pirates from getting sued to hell and back or even receiving prison sentences from the court.
Do you think the police are actually policing the internet?
Even if you didn't mean your local police, and meant a national body like the FBI, the truth is they focus on other crimes (eg. child abuse), and even then they are woefully unable to handle even most of those crimes.
The vast, vast majority of copyright enforcement comes from copyright holders ... not the internet copyright police.
Copyright infinging materials dont go "though" trackers. Trackers only keep torrent hashes and lists of peers.
