About Safe Search
SafeSearch is a feature of
Google Search and Google Images that acts as an automated filter of pornography and potentially offensive content.(wikipedia)
Since then better companies has followed with greater success to leave out search results, that by the US new religions females, is called harmful. (Those who do the most harm here are those not telling about biology and human reproduction)
Many search engines, such as DuckDuckGo and others offer users the option of turning on a safety filter. When this safety filter is activated, it filters out the inappropriate contents from all of the search results.
If users know the actual URL of a website that features explicit or adult content, they have the ability to access that content without using a search engine. Some providers offer child-oriented versions of their engines that permit only (Close to, Admin) children friendly websites.
