One issue to be thought of is if he tells how he hacked the accounts, it would become difficult for him to hack some other accounts in the future. But I have found out that he has a habit of giving out advice to people. I have done some searching and found out (hopefully) who he is.
A simple google search for the email [email protected] revealed this link http://mydomaintest.com/index.php?query=getgamesfree.net with owner douglas
A password reset on that account shows the following accounts listed. do * * * @gmail.com do * * * @aim.com
A password reset on aim.com for user name douglas(just guessing) also revealed the email d * * * *[email protected]
Searching for the name douglas parmele and 5167, brenda gave a result http://welfare.im/dox/index.php?name=communist
There is a reference of froze.us in the dox.
