I find this question similar to Why can't we use the word "problem" in titles?, regarding Stack Overflow's filtering of the word "problem" in a question's title. A similar strategy could be adopted by filtering phrases such as:
- What is wrong -- as in "What is wrong with this code?"
- Why doesn't this -- as in "Why doesn't this code work?"
- Help me -- as in "Help me debug something."
- What am I -- as in "What am I doing wrong with this?"
The likely reason why people ask such questions is because they have a problem and they do not know how to identify that problem. These questions are generally a request to troubleshoot a problem when the asker does not have any clue on where to start.
Notice how such phrases can be easily substituted with the word "problem". Since questions of troubleshooting nature are not explicitly banned, I don't see why bad titles should be rejected if the asker cannot come up with a more helpful question as long as the question is properly tagged.
I would suggest such filtering mechanism to serve as a helpful reminder instead. "You may like to come up with a more meaningful title, if possible."
Back to the question, "Anyone want to clean up some bad titles?". I would suggest we leave it as it is. In most cases, if you know how to formulate your question, perhaps you are already one or two steps closer to your answer.
