This will be live in the next build:

- Deleted questions will be visible to their authors, regardless of those authors' reputation.  They won't be *linked to* anywhere that they're not already linked, but if someone knows where to find their question and it's been deleted, they should always be able to view it.

- Delete-voting within two days is disabled on questions scoring -2 or above, regardless of the voter's reputation.

Automatic deletion of closed, abandoned questions will be implemented shortly thereafter, with such questions defined as those meeting the following criteria: 

- Closed more than 7 days ago
- Not closed as a duplicate
- Score <= 0
- Not locked
- No answers with a score > 0
- No accepted answers
- No pending reopen votes
- No edits to the body or title of the question in the past 7 days
