I remember fifteen years ago I wanted to pirate new super Mario bros for Wii but Nintendo hired a lot of bad peers on eMule, it was impossible to download it. It would download it super fast thanks to the hundreds of fake peers that would upload garbage data, but then when completed it would check it and fall back to 0.2% completed. Super frustrating.
In the end I just gave up because I hate and suck at platformers, why would I ever pirate something that I would never play, but at the time in the forums someone said that with IP address filters it was possible to complete the downloads, by blacklisting all the commercial ip address space and allowing only residential (or maybe they were just living in the right spot, at the time in select cities in my country there was an ISP that ran a fiber optic MAN - metropolitan area network, and it was awesome for piracy, as they didn't block the smb V1 protocol between customers so there were peers that shared gold mines)
