How many levels of “Are you sure” have you seen?

Outlook Web access 2003:

1. I delete a mail, it goes into the folder “Deleted items”.
2. I empty “Deleted items”.
3. But, under options, I still can “Recover deleted items”, or finally(?) delete an item permanently.

Has anyone seen more levels to really delete something anywhere. (Except for journaling systems where nothing is ever deleted.)
