So much for Google's Privacy Settings

I'm guessing the Google+ profile didn't appear in "featured links" (don't know the proper name for the special links at the top) anymore, only in the organic search results.
plus.google.com is probably crawled just like the rest of the Web by Google Search (as it should be), and there is no special treatment for it, so having an outdated result in page 3 for a few weeks after the profile has been changed is likely standard behavior.
The post confirms this since the search result snippet image gives more info that was available when clicking through to the private profile.
To actually delist a page from Google can take a little longer than a week, we renamed one of our pages recently without 301 redirecting and it took a pretty long time for it to be removed from search.
Clearly, this isn't the case.

It looks like telling Google to not show my profile in search results was useless, the only option was to *totally delete it which I have now done*.
