From the Moderator Tools Help:
When should I delete questions?
Closed questions that are of no lasting value whatsoever should be flagged and deleted.
Before voting to delete, please check whether there are any good answers; if so, then the question should be flagged for moderator attention as a potential merge candidate. We don't like to lose great answers!
Also, be cautious when deleting questions closed as duplicates; they can serve as a signpost, directing users to useful answers on another question.
It takes 3 votes, minimum, to delete a closed question. However, the number of delete votes required scales to the number of votes on the question and all its answers.
You must wait for a question to be closed for 2 days before you can vote for deletion. This restriction is removed for trusted users when a post scores -3 or lower. If you feel a post should be deleted despite having lots of votes or for being new, please flag it for community moderator attention.
