To be absolutely clear dashboards are not on Google unless customers decide to put the URL in a blog post or somewhere else on the public internet, this is a non-story.
I.e. no dashboards have been exposed or otherwise leaked by Geckoboard. In order for these dashboards to appear in Google:
1. Customer switches on sharing for a given dashboard in Geckoboard
2. Then publishes the sharing URL on the publicly accessible web
3. Google then indexes that link
In addition to locking down dashboards behind a user/pass or restricting access to only certain IP address customers can, at any time, generate a new sharing URL which denies access to the previous URL.In a related development we've been advised that this story is being touted around by a PR agency - we're still trying to trace who has employed them but we have a reasonable idea.
