For the do-it-yourself approach, you could change the e-mail address associated with each of the accounts you want to delete, then delete them. That would eliminate any possibility of accidentally deleting the "good" account, simply because it shares an e-mail address with a "bad" account. For simplicity, you could change all the "bad" accounts to the same e-mail address.
