The ordinary court system is quite adequate to resolve that sort of thing.
It begins by showing evidence under penalty of perjury that a crime has actually been committed. Then you can get warrants and subpoenas and so on. You don't get to demand that an ISP shut off a customer just on your say-so.
Many years ago, I was the designated recipient for abuse reports for a large institutional network. We frequently got very firmly-worded demands that we shut off the terrible pirates who were smuggling bootleg copies of The Matrix through various IP addresses on our network.
The problem was ... the IP addresses the complaints mentioned, had never been routed. They had never been connected to the Internet. Those IP addresses had never received so much as a ping packet. They certainly were not sharing copies of The Matrix on Kazaa.
The complaints were not only false, but obviously false to anyone who had even basic technical competence to investigate them. They were probably due to a bug in the software the MPAA Agents were using to track down bootleg copies of The Matrix.
Which is to say, some jackhole at the MPAA didn't even check whether they could actually download The Matrix from a Kazaa host at that address, before emailing me a nastygram telling me to take it down. They threatened us and told us we were breaking the law, incorrectly, because they didn't check that the crime they were alleging had even actually occurred.
Naturally, nobody responded when I pointed out that their accusations were false. But the accusations just kept coming.
The "copyright industry" have never even tried to behave as law-abiding citizens with honest legal complaints about other people's conduct. They have consistently perjured themselves, lied to the public, committed felonies against their own customers, demanded dictatorial control over things they don't own (including your own hard drive), and generally acted like a band of clownish goons.
They don't get the benefit of the doubt on anything related to Internet technology, ever.
