We now have a rollup discussion, for reporting the problem, in Blogger Help Forum: Something Is Broken.
Legitimate reports of this problem need to be carefully separated from other known scenarios.
- Blog(s) that are (righteously, or spuriously) deleted or locked - and can be reviewed, using the 4 step process.
- Blog owners who have (for one reason or another) logged in to Blogger with the wrong account, and who do not see their expected blogs in the dashboard.
- Blog owners who have deleted the Blogger account, or individual blogs, for one reason or another.
