I was thinking this was going to be about human moderation in search filtering, but it actually is about engineers implementing manual input into the algorithm to force certain results to never appear or certain results to always appear. I wonder what the consequences of no-filter algorithmic search results in. Google had to tweak its algorithm to avoid disinformation campaigns from spam in the past. Now we're dealing with another sort of disinformation campaign and I don't know a reasonable way for google to tackle it the way it is now.
