I am trying to figure out how these 3 websites did this. They are kids search engines that when you search for a "bad" word it says oops. The 3 sites are: http://www.dinosearch.com/results.php?cx=partner-pub-3681952026935924%3A1825239694&ie=UTF-8&q=fuck&sa.x=0&sa.y=0&sa=Search http://www.kiddle.co/s.php?q=tits http://www.kidrex.org/results/?q=fuck&cof=FORID%3A10&ie=UTF-8&safe=high&cx=005531940451544459472%3A_wxzudlmale&sa.x=45&sa.y=11 Thanks for any and all help.
That's because they have "Safe Search" turned on in the CSE. I think it's turned on by default. You can also do the same thing with Bings Web Serach API
