Porn piracy is rampant all around the world, and even though the US pushes a deluge of crappy porn into the universe, we're not the only ones. France and Japan have their own pornographers, but they're not immune to piracy, either. So, what do they do about it? France says, eh, it happens, Japan says fuck you pirates, here's a lawsuit! Japan pornographers have thus taken the RIAA model of media ownership and launched an attack on South Korea, while France has, obviously, surrendered. I'd say that the content has something to do with it: Japan knows there's no other source for tentacle child rape in the world, so they're going to protect their valuable assets, but, come on, who can't get a French woman naked in front of a camera?
