The most completely batshit insane groups I’m willing to google anymore are flat earthers, young earth creationists, and Facebook mom groups, and google happily indexes and returns favourable results for all of these.
Even looking at off the deep end alt-right content like men’s rights, red pilled, trucker convoy, anti-masker, Tate, etc, google has zero issues return favourable results for all of them in a private window.
Really begs the question of just what level of illegal shit this dude is trying to get google to return.
