After Microsoft’s recent criticism of turning bing.com to a porn portal, Microsoft has moved into serving potentially explicit images and video content from a separate single domain, explicit.bing.net. This is invisible to the end customer, but allows for filtering of that content by domain which makes it much easier for customers at all levels to block this content regardless of what the SafeSearch settings might be. This makes it much easier for companies to use filtering software to block unwanted content if SafeSearch has been turned off.
Additionally, Bing will begin returning source url information in the query string for images and video content so that companies who already use this method of filtering will be able to catch explicit content on Bing along with everything else they are already blocking for their customers.
