Report: Requesters without requests

Report: Requesters without requests

I recently deleted THOUSANDS of Active Directory accounts from my domain and would like to clean out the requesters in Service Desk that do not have any requests.  Then import my Active Directory again to get a "fresh" list of requesters.
 
Can I recieve a custom report to find requesters that have no requests in the system so  I can delete them?
 
Thank you
