I typically have safesearch turned off and I recently had DuckDuckGo give me porn I wasn't looking for for two image search queries (Google did not give me porn):

• Tiny spy camera (I actually wanted images of cameras)
• Ficken liquor ("Ficken" is German for "to fuck"; I was looking for images of the alcoholic beverage so named)

Of course, I've been on the internet for a while and was neither shocked nor offended.
