Update: This policy is now in effect, and the question will be closed. The proposer should update the FAQ accordingly.
This is a policy question. The proposed policy in the question (or answers) will be adopted in the case that after 3 days it received at least 5 up votes with a 2/3 majority in favor. Please upvote or downvote this question based on your opinion of the policy statement as presented (not based on whether the premise of the question is reasonable)
We have had a number of instances that a question by a user is down-voted or closed, and the OP reposts the question in place of modifying/improving the original one. Sometimes the previous question is also deleted. I think this is a kind of circumventing the system, why are we down-voting or closing if the user is going to delete the question and repost it? It also takes more time from us because we have to read the post again. The comments are also lost.
The right thing that OP should do is to modify/improve the question and address the reasons the question is closed and then ask for reopening (if there is still a disagreement and OP is not happy with the result, the remaining issues can be discussed on the meta). (Is there any reason for deleting and then reposting a question other than hiding something?). Therefore I propose the following policy:
POLICY: A reposted question should be closed as soon as possible. They should not be answered. The OP should be asked to modify the original post in place of reposting the question.
ps: I understand that in some cases there might be acceptable reasons for reposting a question (thought I personally cannot think of any at the moment), if you have one please post it as an answer.
