I've been looking through this Cregg website (who have taken over the website Cramster), where students can ask homework questions and get worked solutions in return for "ranking" or possibly paying $1 or so.
I found this question to be among the worst:
There is nothing more to the question than this photo of what appears to be a test in progress.
This raises the hypothetical question:
Question: Imagine someone posted this photo as a question on math.SE (with no other information). Should this question be closed for lack of effort?
As far as I'm aware, precedent has not yet been made on closing a homework question based on lack of effort. So this is why I ask: I would like to know if there is any point (a lower bound) in which we would say "enough is enough -- there must be some effort on your part too"?
Think this is a once-off? See also, here, here, here, here, here, here, here, or here. This is just a sample of questions over the last five days where it is clear that the answer could simply be copy/pasted into a web-browser (possibly to be graded).
