I've entered data for OE in the AppDB, but the link still can be found via Google and still gives the same error message.
That's because it's deleted but AppDB returns the wrong HTTP status code, letting google think it's still there.
Resubmit the application if you want an entry for it. I would say a patch is required to return 404 for deleted applications.
