In recent days it seems like the Close post queue have been rather full with questions. A lot of times the question are years or months old, and are not even bumped to the front page. I frequently reach the 20 review limit for Close queue, while I have never get that much in any other queues. In fact, sometimes there is as much as 20+ questions in the queue that allow the limit to be reached in just a single session.
Is there some reasons behind the recent flood of the Close queue? Is there some sort of Great Purge in effect that I am not aware of? Why are so many old questions get closed suddenly?
