I suspect it more a case of
a) using exact sort expession matching and not picking only the popular sites.
c64 pc gets retocomputing,
not who has the latest windows 64 bit computer for sale.
b) not having paid advertising/sites
come first like google or exotic sites.
c64 game “catch a bunny” ages 8-13 (fake game)
has only a tiny link after between all the adult porn
and pop up pages.
Notice this link is un-certified we will not let you enter that site.
