Our resident troll posted a question today which I thought he had asked before, and that seems likely because Reg closed and deleted it.
While Reg was dealing with it, I tried to locate the earlier example. Finding questions which have been deleted appears to be remarkably difficult: presumably that's by design.
However, since it's possible to get a "That question has been deleted" page, and 10k users can see them under certain circumstances, deleted questions must still be held in the database.
An SEDE query which finds all of a user's posts, like
select p.Id as [Post Link],p.Id
from Posts p
p.OwnerUserId = 23135
will find some relevant questions, but only those which have not been deleted.
Is there any way of finding deleted questions?
