Of course the pages are in their index. Google isn't a curated walled garden. I expect every page on the public internet to be in their index.

The question is one of rankings. The only time there is a problem is when a spammy site ranks above a more relevant site for a particular search. If I enter a very specific query that only hits a spammy site, then I should see the spammy site, because it's there. Google is a search index, not a "visitors guide to the internet."
