A homework question posted 2 hours ago has been locked: https://math.stackexchange.com/questions/21853/change-of-measure. Is it the level of the question (i.e., graduate level) that earned it this designation or is there a distinction between the manner in which it was asked and other homework questions?
It looks like there has been quite a lot of discussion about how to handle hw questions, so I might have missed some community decision that would make it clear why this question was locked. It just seemed quick, giving the OP less than 2 hours to address the issues raised in the comments.
