Google Instant is Google’s search enhancement that shows results as you type. Before Instant, when you’d type a prurient term such as ‘nipples’, you’d be shielded by the final ‘Press Enter to search’ before Google would give up its nipply bounty of links and images. But with Instant, those results show up right away. So Google in all their wisdom, has seen fit just to blacklist that word, along with terms you’d expect, such as ‘penis’, ‘vagina’, and ‘smut’. But what’s unexpected is some of the other terms Google has decided to blacklist in its diligent struggle to shield the public from naughtyness. Hacker magazine 2600 has been tracking these blacklisted words.

(N.B. You still can find these search results if you ‘Press Enter to search’, but they’re conspicuously absent using Google Instant)

Try these for yourself. Go to Google.com and make sure ‘Instant is on’:
