We have a user who is asking lots of questions like Cournot competition question or Consumer theory with lump sum fee
I don't like them (the questions)!They are homework questions that nominally satisfy our policy (effort is shown) but contribute essentially nothing to the long-term value of the site. Rather than taking the time to type the solution, we just get scans of exam papers or handwritten workings. So while there may be some "effort" in answering the question, there is essentially zero effort in contributing to the site, which makes me disinclined to offer any effort in answering.
Is this the kind of content we want on the site? If not, does anyone have any views on how our site policy should be modified to kill-off such questions?
