Google Analytics does not index content from the Hacker News website. Content on Hacker News is sometimes available for a limited period of time through popular search engines such as Duck Duck Go and Bing's Instant Answers, but usually only in the form of text and not images. Search engines like Google can't read pages with AJAX, which is what most sites use to make their web pages dynamic and interactive. To summarize- google can't see things that you don't want it to; hackers might; maybe Duckduckgo or bing will show it for a second-long somewhere hidden in some corner where Google won't see them-- but if they do they'll be off by seconds.
