9,000 category pages were definitely doing all I said. These categories then infested every page via templates. What use are categories when a page has more categories than it contains words in the article?

Re your aluminium example, it's true indeed that  when you save aluminium you're saving its compounds, minerals, alloys, and everything that was used to make aluminium, and an article elucidating this and all other green aspects of the subject would be most welcome. What was not welcome was bulk copies of absolutely everything from wikipedia remotely related to aluminium follwed by copies of every wikipedia page those pages had links to.
