How about not filtering my search results when I am doing general inquiries? Just because a website or image may have an explicit meaning in your eyes, doesn't mean that it isn't pertinent to the thing I'm searching for.
How about you just turn the filter off
Safe search off, searching for the word assole. I don't see an asshole, not even Mr Bush is showing up or a picture of the largest asshole people on earth. Now, go do the same on Bing with filtering off and tell me what you find?
