This is just for fun sake. Would love to see what is the most duplicated question? Some may question the reason behind it? It can be a learning link, where new user can see how two question may sound different but have similar meaning. What type of question not to ask. Further more when you type a question, the tab on top that shows "questions that may already have your answer" is not fool-proof. The best duplicate can be spotted on related question, which is after you have posted. That time either you realize or some one will flag your question.
The almighty Data Explorer has answers for you: Posts that are the target of the most duplicate closures.
As of this writing, only the following questions are the target of more than one duplicate closure:
- What's the difference between the FMA and FMA Brotherhood series?
- How did Nagato gain his Rinnegan?
- What happens when Naruto is talking to the Kyuubi?
- How are Chaos;Head, Steins;Gate, and Robotics;Notes connected?
(Since this is a small site, the results are obviously sparse and not very interesting. A site like Stack Overflow has much more interesting results.)
