We had the same problem on our old site. Over the years there have been so many variations on the pop star and pregnancy questions that were virtual repeats.
Then there were the repeat questions about religion, especially, "What's the difference between Catholics and Christians?" Those were doozies because even when it was pointed out that Catholics are Christians and you explain the difference between Catholics and Protestants, they would still argue the toss about it.
The Justin Bieber questions that were asked, ad nauseum, when I first joined Ask faded when his fans ran out of stamina and fickled their way to One Direction. They asked exactly the same questions about 1D that they had about Bieber.
I think duplicated questions are inevitable when you have multiple users, and it may actually be a sign of the site's health. It means that casual questioners are adding their bit to the input of the regulars.
