They figure that, if they can't regain access to the blog, then Blogger will be willing to simply delete the blog - and everybody will be happy. They appear to have overlooked the repeatedly stated policy, which promises us that our blogs will be ours, as long as we wish to own them.
The problem is, blog deletions are as sensitive to illegal action as account recovery - and illegal actions are a very real threat to our blogs.
Blogger exercises due diligence, in requiring proper authentication for Blogger account recovery.
Blogger can't delete a blog, any more freely than give control of a blog.
Any requested deletion, of any supposedly owned blog, must be no less controlled.
Blogger promises us
Blogger accounts and Blog*Spot addresses do not expire.This means that our blogs will not be deleted, or transferred to the control of another person, without careful validation of the person requesting the deletion or transfer. If the other person cannot prove rightful ownership of the blog in question, Blogger is not legally entitled to delete the blog, any more than they are entitled to transfer control of the blog.
We are permitted to own and publish our blogs, without any minimal required activity, and without any required proof of our real life identity. We are entitled to publish our blogs when we see fit - and are entitled to come back to our blogs after any length of time - if we are able to authenticate ourselves.
Blogger lets us publish, at any rate we prefer.
Blogger will not harass us when we are inactive, whether or not anybody else offers to publish to our URL with more vigour. Neither will they give anybody else control of our blogs, either to publish - or to delete. Similarly, they won't give me - or you - access to somebody else's blog, or harass somebody else.
If you find yourself unable to access your blog, and delete it on your own, try using the improved Google account recovery wizard, before asking that Blogger delete your blog for you.
In limited cases, the Google tool Removing Content From Google may be useful. Finally, concentrate on making your blog or website more useful, and organically improving your reputation.
