Once you remove the 0 score questions (ones that are going to be deleted anyway within a year) we are left with a measly 2153 questions2153 questions it's really just a drop in the ocean.
I do not support automatically deleting anything that got a bunch of upvotes and views, the list is tiny and the community can easily work through this - I do not want another deletapocalypse.
So, the main question we are left with is: should we be deleting closed "0 vote" questions more aggressively than we do general unanswered 0 vote questions (happens after a year).
The beauty of the current system is that it is easy to explain. I worry about adding such a rule ... it would also need a bunch of complicated sub-rules like
- no active re-open votes
- not flicking from closed to open to closed.
- not a migration stub (that gets nuked anyway)
- not merged
I do not find the large amount of complexity this introduces is worth the gain of removing 8000 questions. Keep in mind, when questions are closed they are often negatively voted so they get cleaned earlier.
