It seems, from the number of upvotes that this question has recieved, that the community shares your frustration with the situation and agrees that a policy should be made. I propose that we remove the citation when it is irrelevant and when there is a primary source to quote instead, such as in this question:
How much of this world is really ordained by Heaven?How much of this world is really ordained by Heaven?
If an original statement is taken from somewhere (if there is no higher authority to quote other than the poster on the website), a citation should be provided to the post.
