Finding Old Accounts

I used to multibox, and had around 12 8/8 maxed accounts unnamed with various shatters whites. This was years ago and I have forgotten the e-mails to them, though I know I used a disposable website. Is there any way for me to retrieve these? Maybe E-mail deca asking for accounts created under my ip?

Won't work most likely

You gotta know the name or email to make any progress
