I'm not necessarily saying I don't believe you--obviously you'd know more about working there than I would. But can you explain to me why in 2010 if I googled "evidence the moon landing was faked" I got a huge list of conspiracy sites, and now if I Google the same query I only receive articles and websites alleging the exact opposite of what I searched?
I currently work for Youtube. We identify conspiracy-seeking queries, and then boost results from authoritative sources. Don't see why we wouldn't also be doing this on Google. Maybe people don't bother searching for things when the results suck (or maybe they just use alternative means of searching)?
