There are sometimes rather low quality questions appearing in the bounty section. Today these are this and this. In my opinion both require quite a bit of work (such as a discussion in the comments) to make them understandable and answerable. In normal conditions they would be closed, but, since the bounty has been already promised, they cannot be closed till the bounty expiration (probably a week from now).
Wouldn't it be better, if one could vote to close bounty question, provided that the bounty is reimbursed to the author, if the question is closed?
