The account actions may be required with the blog deleted for a suspected TOS Violation, such as hosting malware, porn, or spam - or locked because of "suspicious activity" on the Blogger account.
Why was my blog deleted? I never got proper notice!Too many people depend upon email notification - and may not receive proper notification, in all cases.
Blogger provides a dashboard based malware / porn / spam classification notification / recovery process, which may not be available for everybody. Similar to malware / porn / spam classification, there will be issues with DMCA violation notification.
This is also a problem when accounts are locked for "suspicious activity", and when blogs are locked for hosting malicious third party gadgets.
There are several reasons why some blog owners won't get notification of their blogs being deleted or locked, by the various Blogger / Google security processes.
Nobody should expect advance warning of any action being taken.
Besides notification limitations, nobody should expect to get advance warning of action being taken - as this would simply encourage the intentional spammers to never request review. Intentional spammers, if permitted, would play 3 Card Monte, endlessly, with their spammy blogs.
Both the notification, and advance warning, limitations contribute to confusion about the various Blogger / Google security recovery options. All email based notifications may not be properly delivered.
The owner of any email account, which may not deliver email properly, is still responsible for reading any important email messages.
Some blogs are owned by accounts which use intentionally bogus email addresses.
Too many Blogger blogs are owned by Blogger accounts which are based on inactive or nonexistent email addresses. Owners of these blogs will never see email notification, when they - intentionally or not - make themselves anonymous.
Some email clients may misfile an incoming email message.
In other cases, some people may get the email notifying them of problems - but their email program may misfile the email, in a folder which they may not check, regularly. In some odd cases, somebody other than the owner may get the email.
Blogs owned by teams will be subject to action against any one member.
In team blog ownerships, any blog owned by the team is subject to action, against the Blogger / Google account, used by any team member. Blogs affected will simply disappear from the dashboards of all team members - with no opportunity provided for appeal or review.
Some blog owners maintain too many Blogger and email accounts.
Finally, too many blog owners maintain multiple Blogger / Google accounts, and are not completely sure which Blogger account may own a given blog. These owners may not even see the dashboard based "Deleted Blogs" button / link, because they will be logged in to the wrong Blogger account.
Each blog owner is responsible for any problems, regardless of cause.
Not all of the above scenarios are entirely the fault of the blog owners - but the blog owners are the ones who will have to deal with the resulting problems. It's possible that this may seem unfair - but it's reality.
