I mean I guess running a torrent thingy works, but the people doing any kind of "good" are people who actually contribute pirated materials, like uploading random documentaries and things someone has to YouTube. Or being one of those people who goes and sees a movie and records it (lol), because they're making something (usually entertainment) available to at least a couple people who can't otherwise afford it, which you could see as legitimately morally good, especially since it risks punishment.
