Recently, we've seen a variant on the account lock / deleted blogs problem.
I made one of my friends an admin for my blog. When Blogger deleted His Blogger account and his blogs, they deleted my blog also.Here, we see the possibility of detected hacking, affecting other members in a team blog ownership.
If someone sets up a blog, then invites his friends to be administrators, everybody on the team becomes equal owners. This can also happen when one person maintains two or more Blogger accounts - whether accidentally or intentionally.
That's the definition of a team blog - and it's one known problem with team blogs. This case shows us another problem with team blogs.
If somebody on the team has a Blogger account locked for detected hacking, all blogs owned by that account are taken offline, for security checking. Any blogs owned by that account are going to simply disappear from the dashboards of all owners - because all owners produce the same security risk, to any owned blogs.
When a Blogger account is locked, review of blogs owned by the account starts after the account is unlocked. If the team member with the locked Blogger account doesn't get the account unlocked, the blogs owned can't be reviewed.
Once again, we see why it's a good idea to only have active team members, as blog owners.
