Although I wouldn't say I'm convinced beyond a reasonable doubt, it certainly appears (at least to me) more likely than not that Nefario delisted all of Goat's assets just to get back at Goat for an unrelated issue and defrauded GLBSE customers that owned those assets by completely disregarding his obligation to protect the value of their ownership interests in those assets. There is no way he could not have known that the delisting would reduce the value of those assets.
