Only delete unvalidated users that never posted anything

http://drupal.org/project/logintoboggan#commitment

I think there's a reasonable case for this because if you delete users that have submitted comments those comments will then be attributed to anonymous, which you might not want. Any chance of a patch?

The first thing that comes up to my mind is that this use case maybe can be fulfilled using Views and Rules:

Event: cron runs.
Conditions: A set amount of time has passed.
Actions:

• Retrieve a View with users to delete.
• Delete these users.

If this could be set up, a default View and a default Rule could be added to Logintoboggan. And then all you have to do is to adjust the View, so it only shows users who never posted.
