I just encountered this as I was having issues with google results. I thought maybe something is wrong with google and people are switching yo duckduckgo.

Seriously I just searched something on google and second page of results are total crap. When I switch to duckduckgo with same keywords I get relevant results.

For the record, keyword I was searching for was "first man curiositystream", on Google I get a bunch of fake websites on second page of results, sited with lots of random words in description for seo hacks.
