This is why you should always have backups. I'm astonished that this post doesn't have any discussion on the security implications: they say that the database was not copied, but I'd still be nervous about this--presumably it contained access tokens to Dropbox as well as email addresses. If it didn't I'd still want to hear verification of that. Their homepage claims "Secure" as one of their four main features, which is rather belied by the presence of a default administrative user on their database server--not to mention that the database itself seems to have been publicly accessible from the larger internet. This seems like it would have been prevented by simply putting a firewall on the server and not opening unnecessary ports.
