In case u haven't tried this...

Go back to the noobs u have hacked in the past and look at their email and use their old password to see if its their email password [ hope u kept their old password saved somewhere] then change their email password then try their email with their new password you changed in amazon to see if they have an account there or itunes, ebay, or any other site that u can profit from

i got lucky with one of my past hacked accounts and found out that the user had about 13 bucks on itunes and this other one was a 10th prestige in black ops xD it was helpful
