My top question (most views and upvotes) was marked as a duplicate almost immediately after being asked. It went on to get hundreds of thousands of views and multiple answers with tons of votes. It is still marked as a duplicate to this day. My top few answers are similarly on questions marked duplicate, off topic, etc. Seems the culture of stack overflow is that everything useful has been answered elsewhere. Therefore, if a question is useful, it must be a duplicate or pff topic.
