I just found this post on Stack Overflow and realized that the OP asked the same exact question 9 minutes earlier on Server Fault. Then some days later he answered both of his questions and accepted them.
The question title/body and the answers are perfectly identical. Clearly it was a copy and paste. Both questions/answers are upvoted and there are other answers too. What should I do with them? Flag it? Which one? Or should I just leave them alone?
