I remember around 2005 there were marquee displays in every lobby that showed a sample of recent search queries. No matter how hard folks tried to censor that marquee (I actually suspect no one tried very hard) something hilariously vile would show up every 5-10 mins.
I remember bumping into a very famous US politician in the lobby and pointing that marquee out to him just as it displayed a particularly dank query.
Still exists today. It's a position called Search Quality Evaluator. 10'000 people who work for Google whose task is to manually drag and drop the search results of popular search queries.
