Oh sorry that was me. I made 900,000 blogs about bitcoin and then was like "Nah. Too much effort." That, and now I'm all about my bitcoins-for-doughnut-cheeseburgers business. You'd pay a bitcoin for this, wouldn't you?
I can't believe nobody has thought of this before. I'm going to have this market cornered.
Actually, it's probably because Google tends to cull new "high traffic" search terms en masse, rather than one at a time to prevent people from using trial and error to brute force SEO optimization. There was probably 900k auto-generated sites from search engine optimization companies. They watch google traffic for new search terms that have a disproportionately low amount of pages for search traffic and then use those terms in generated pages to boost their client's websites. Google always tries to detect and remove that crap, so it's a cat and mouse game. Also, I'm pretty sure that sharks are involved somehow.
