Google is now directing its review teams to flag content that might come across as upsetting or offensive in search results. The review teams - comprised of contractors known as "quality raters" - already comb through websites and other content to flag questionable items such as pornography. Google added a new category, "upsetting-offensive," in its guidelines for quality raters. For example, content with "racial slurs or extremely offensive terminology" could now get flagged as such.
