I just saw this thread: https://math.stackexchange.com/questions/970464/parallel-tangents-and-curves and there were discussions in it on whether or not it was appropriate to downvote an answer which was fully worked out for a questioner who seemed to do no more than post a homework question without thought/etc.
I'm new here and don't have a horse in this game, but I'm curious: A: Should we in general discourage giving full answers to these questions which appear to be cut/pasted homework with no indication as to what the author has tried?
and if so, B: Is downvoting said answers an acceptable form of said discouragement? The instruction page on downvoting doesn't seem to indicate this as an acceptable use
