Meatponder, I do understand - but the problem is the flexibility of the english language. Think of words like cock, wood, bush, greek, russian, balls, melons... the filtering by word would be almost impossible because the language evolves. How could they know that someone searching for Bush Melons would be looking for sex or for recipes from the president for deserts?
You can filter a very few terms that are clearly porn (porn, porno, fuck, tits, anal sex, etc) but is pussy about cats or human anatomy?
