Since ID questions are off-topic, why are the moderators not removing ID questions immediately right after a user posts them?
This question has been asked 16 hours ago but it's still online.
They will automatically be removed after 9 days, provided that they are closed and don't have a positive score. There's an automated process for this nicknamed Roomba, no need to bother the ♦ moderators with this; it's not like the questions are harmful. They just won't be answered. Also, if the question's score is -4 or lower, it will not appear on the homepage, only on the other question lists, so most users won't be bothered by them.
