Please note that the Community user now automatically deletes *all* questions meeting the following criteria network wide:

http://meta.stackexchange.com/questions/78048/auto-deleting-old-unanswered-zero-score-questions-after-a-year

- less than (question age in days * 1.5) views
- 0 score or lower (or a score of 1 with a deleted owner)
- no answers
- 1 comment or less
- asked more than 365 days ago

This is in addition to deleting unanswered, *negatively voted* questions with zero answers after 30 days, which has been in place for a while.

Since the Community user is considered a moderator, it isn't possible for post authors to undelete posts that have been autodeleted in this manner, so they'll have to flag.
