I have reservations about drawing attention on meta to a large number of closed posts that perhaps should be considered for deletion.
]]>It takes 3 votes to delete a closed question and there is a 48 hour waiting period after closure before deletion votes can be cast. Since candidates for deletion lose visibility fast, it's a good idea to occasionally check the deletion list in the moderation tools. Candidates for deletion can also be brought up on meta to increase awareness and discuss borderline cases.
For spam, it is best to flag as spam. After 6 flags, the question is deleted and the poster gets a 100 point penalty. It only takes 15 points to have the ability to flag as spam and there is no 48 hour waiting period.
]]>If you really feel that a question should be deleted quickly, you can always flag for moderator attention. We can delete it at any time.
]]>May we consider the practice of not only closing questions (I have in mind those which are not of the contentious type...) but also actually delete them?
