Someone asked a reasonable question related to this several months ago. From the answer, it seems that none of us here has any control over the process, or the algorithm.
Another approach has occurred to me: How heavily can these "recycled" questions be edited?
For example, if I edited such a question - one that I thought hopelessly clueless - could I edit it in such a way that it could be closed for being "off topic", or a "shopping request", or something else that was clearly a question to be closed? Similarly, a "zombie question" could be edited to create a good and useful question... but the dividends for time invested just aren't there. What are the rules on this?
