This is a question that I have been meaning to ask, and now I've just seen a set of questions that nicely illustrate the problem, so here it goes.
Everyone that knows our homework policy will be able to see that the questions linked below are off-topic:
The posts are pure copy-pastes of a question in a book, without any effort by the OP to solve it and/or explain what the specific issue is. Our close-vote enabled users are fairly quick to respond so these posts are closed within a few hours, so no real problem there.
The problem that I do have is the following: in the time that the question is open, sometimes the questions get answered, usually by inexperienced users that genuinely want to help. This will hurt the site and therefore should be stopped, but how can we deal with this?
Let me elaborate a bit why it is hurtful: if people ask bad questions and they still get answered, then people will just continue to do ask bad questions, even though they are not strictly 'allowed' to.
However, I'm not sure how to tell our inexperienced users to stop answering the questions, because I don't want to kill their 'getting-started' enthusiasm. So how can we 'educate' our inexperienced users such that they don't answer questions that don't belong here?
