it doesn't make sense that doing a noindex on low quality pages would help your site rank better. Google is telling us to do it, but they can still crawl the pages.
So what we're telling Google is:
1) I have low quality content on my site
2) I'm blocking it from you for better rankings
3) Users can still see this low quality content
4) I'm trying to trick you
