There is an auto-deletion process that removes open, abandoned questions, and under certain circumstances, closed questions. But there are many closed questions that are preserved. Looking for those to review for rehabilitation or clean up is not always easy.
Let's say that I'm in the process of curating a particular set of questions related to a tag I'm interested in. I can see that I've got a number of deleted questions, but I'd like to review them for editing, retagging, reopening, or possible deletion, separate from the ones that the auto-deletion process will eventually take care of.
What query or queries can I use to find those deleted questions that will not be automatically deleted?
- Turbocharging the Roomba: solutions for premature deletion - Shog's answer spells out the conditions under which questions may be automatically deleted. The same text appears in the help on sites, e.g. https://stackoverflow.com/help/roomba.
