Take a look at the following question that was migrated to here from Operating Systems SE:
Unfortunately, it looks to me like that question has some issues:
Copy-pasted question. The CS.SE question is basically a duplicate of a question that was previously asked on StackOverflow: https://stackoverflow.com/q/25464848/781723. Indeed, the CS.SE question copy-pastes the text of the question. The body of the CS.SE question does not seem to add anything substantial over the Stackoverflow question, and it does not articulate a specific question about the answers that were previously provided on StackOverflow.
Copy-pasted answer. Not only is the question copy-pasted, but the accepted answer to the question on CS.SE is an exact word-for-word copy of the accepted answer to the question on StackOverflow. To be clear, I'm not saying Gilles has done anything wrong. I'm just suggesting that it's not clear that it is adding any value over the Stackoverflow question.
Not much value added. I can't see much value that this question adds, over the prior StackOverflow question. It's the same question, with the same answer. The statement of the CS.SE question doesn't add much value. There is only one other answer on CS.SE to this question, but I'm not sure it is adding much; if I read it correctly, it is just saying "the answer over on StackOverflow was correct".
Overtaken by events. The question on CS.SE might be based upon a premise that is no longer accurate. In particular, it refers to an answer from shekhar suman on the StackOverflow site, but there is no answer authored by shekhar suman on StackOverflow at present. At present, there are only two answers: one authored by Gilles, and one authored by Martin James (with a trivial edit from shekhar suman, to change the font for one word). I don't know if shekhar suman deleted his answer, or if the original premise was faulty, or what, but at present the CS.SE question does not make sense, due to this reference to something that doesn't exist.
What should we do about this question? Should we close it? I'm not immediately seeing a good way to fix these problems and save the question. What do others feel?
