At Google, we take your privacy and security
very seriously. Therefore, we're committed to returning accounts only
when we're sure we're giving them back to the accounts' owners. Because
Google doesn't ask for much personal information when you sign up for an
account, we don't have many ways to verify that you own an account.
in other words, if you can't use either the account
name / password, or the
email address, to recover access to the Blogger account, then you may be out of luck. Blogger has no legal right to
give "you" access, if you cannot prove ownership. Deletion is not an alternative, either.
no simple solution here. You might be able to use the (recently
improved) Google account
recovery tool, if you remember what the email address was, and enough auxiliary
details. We hope that you can see the bigger picture, and read the FAQ,
