SE Spam Mystery

Well, I was following up to see why I got a site referral on the query "the abrahms that do infomercials" (now I'll do really well on that query, although I still don't know who that might be, and obviously a search engine is auto-correcting my name), when I saw that the results were filled with odd Chinese pages filled with words and no content.

I thought it might be search engine spamming, but I don't understand how - because there are no links from the page. Nor even a title tag. So there's no way that PageRank can be gained or distributed, that I can see. It's puzzling me.
