Definitely fuck them. The largest pro-privacy, entity really, ISP in Sweden had them sued for copyright trolling. I believe that Elsevier in response blocked any Bahnhof-customers. Bahnhof blocked Elsevier traffic with this tenner: http://elsevier.bahnhof.se/.
This was a big deal when working there because Bahnhof had a track record of not honoring requests to give out personal info or blocking any sites. The CEO also secretly recorded the FRA, our equivalent to the NSA, as they were trying to make a deal under the table to be able to spy on customers. There’s even a video recreation (the server he’s holding used to host Wikileaks)!
