Only 6? Really? I'm pretty sure /r/piracy existed and had more users than that in 2011.
Shit... I could be one. I got banned from /r/Gaming around that time just for telling someone what specific .BIN file to search for to get their playstation emulator running, despite others mentioning the same thing and their rules only saying you can't post links.
They aren't going after the users, they are suing the ISP. The comments are about the ISP's leniency towards torrenting, so they are trying to find the users to validate their claims and add the comments as evidence to the case.
