Appeal Court Affirms Piracy Liability Verdict Against ISP Grande

I'm not familiar with the original case but was the legal system ever involved for the customers?

It sounds to me like it was only Rightscorp (sidebar, what a fittingly dystopian name for a company like that) sending letters to the ISP, why would anyone be compelled to act without a court order?

Can I just start sending notifications for random IP's to their respective ISP's and hope I get lucky with one of them torrenting movies?
