Hi Paul

I tried manually deleting a user and the date the user was deleted was recorded in the user last modified date. How were the use's deleted in your case?

It is also possible to purge deleted users data to delete selected data of deleted users - if the first and last name was one of fields selected for purging then the user data wouldn't be identifiable.

A record of the user is kept under Site admin > User data management > Purges and Deleted users accounts

This report is able to be modified so the user last modified date can be filtered on.

regards
