I am thinking of a particular string of questions, such as here, here, and here. This particular user has asked over 10 questions of this flavor in the last 3 days, and many of them are being completely answered. While I realize that it has not been the nature of this community to carefully identify and neglect to fully answer homework questions, I think that this might be excessive.
Is there a place where we draw the line? Further, what would be done to discourage this sort of behavior? In this particular case, I have this feeling that excessive answering will lead to a lack of actual learning, which I believe is entirely contrary to the purpose of this site.
