If mariotehplumber is behind the Grinch Leak, real or fake, I'm fine with it, because he'd face legal repercussions either way. To put it in the words of a Tumblr post I saw:
If it’s real, he’s responsible for leaking sensitive information from Nintendo, can get sued by Nintendo AND by his friend (or friend of a friend or complete stranger) Eric who he had either tried to frame or who is also in trouble for breaking NDA.
If it’s fake, then he gets sued like hell by BOTH printing companies thought to be a part of this fiasco because it severely damages their reputations and their relationship with Nintendo.
