Google is a public service search engine & It is not promoting or affiliated with such sites. Think of it as a crawler (a robot) that will do just what it is told to do. Google Bot will follow every page on the world wide web & their algorithms are mature enough to filter these websites at once.
If you find yourself offended with such results then just filter them through your google preferences. Turn Safe Search on.
It's stupid to even think of blaming google just because you found that in a certain serp. Of course they are taking measures to stop such results from appearing in it's safe search index.
