Put the pieces together. They probably did that because any kid with half a brain would otherwise do a 'translation' of playboy.com or hotasianteens.com to bypass the filters. When you translate a site, the results come back under that site. If you tell it to 'translate' sexygrannies.com, you'll get back page with the text in whatever language you instructed as plus all the pictures, and as far as the filter knows, it's all coming from google.com.
They don't care what language they translate it to, because despite what they might say, they are NOT reading those sites for the articles.
Pictures of naked girls surrounded by gibberish text is just fine for any red blooded teenager, you should know better.
