Well, at least it's not EXACTLY the same as Arceus, at least. It actually changes the time of a move.
But you know, I have to wonder, why do they do something like that? If they were going to "legally threaten" people into taking down information until the US version is released in six months, why would they not just release them at the same time? -_- They don't have to do that to people, and it doesn't keep people from seeing stuff they want to see for a half year after the game is released.
But yeah, Nintendo has lawyers, and they don't like it, and I guess that's all the reason they need. Sheesh...
