Bug found in deletion of an account with similar names

I have 2 domains www.jamals.com (user: jamals) and www.jamals.com.pk(user: jamalspk)

I create both of above accounts with the username jamals and jamalspk but after deletion of jamals the jamalspk is also affected in DNS entries as well as the databases relation with account are disturbed.

after deletion www.jamals.com (user: jamals) I found .pk only in the dns configuration file and the default structure of dns file is also disturbed.

Please consider it and fix in the software.
