How do we know that was the cause of his adsense ban? If you read Google's own page on prerendering: https://developers.google.com/chrome/whitepapers/prerender https://developers.google.com/chrome/whitepapers/prerender "If your site includes a third-party script for analytics or advertising, in many cases you shouldn't have to make any modifications to your site—the third party will simply modify the script they provide slightly to make use of the Page Visibility API. You should contact the third party directly to see if their scripts are prerender-aware." I'd assume Adsense would of implemented this and would be prerender-aware.
