To me the automatically generated content is the most interesting aspect, because almost all sites do it to an extent. How many generate rss feeds, category and tag pages, and other ways of presenting the same snippets in different contexts. A little is essential, but a lot of that creates duplication issues and thin pages. Think of an article tagged "strange widgets" and "bizarre widgets", when it's the only one with such a tag. It's an issue of poor usability (and waste of the crawl budget) when your website creates thousands of similar-looking stub pages.
So I wonder if that's the sort of thing they're getting at? Automatically generated could mean other things instead.
