if you ping the hub (any open hub) with a full RSS feed, then THAT (full RSS) is what gets pushed to your subscribers, and one of those can be Google but can also be your scraper.
I keep the full Atom feed URL private (unlike the WP plugin). Scrapers have to know the URL to subscribe it. I just add the full feed to Google Reader (for debugging) and Google Webmaster Tools (as sitemap).
