You've probably seen those "purity test" sites before, where they ask you a bunch of weird questions related to a certain topic and then tell you how "pure" you are about something. Well, Google has its own purity test and it's based on whether your URLs are filtered by its SafeSearch mechanism or not. Thus, the Domain Purity Test. This hack runs a search for the URLs in your domain and assembles the results (or the first fifty URLs, whichever comes first) into an array. It then searches for each of the URLs in the array with the SafeSearch filter turned ON. If an URL doesn't appear with the SafeSearch filter turned on, it's booted into the "Naughty" array. If it does appear, it's put into the "Good" array.

(Since this can run up to fifty URL checks, it'll take a couple minutes to run. You won't get an instant result unless you run domain search that's a stop word (sex.com) or the API key has run out and you're not using your own.) At the end of the search you'll get an estimate of how "pure" your site is, according to Google's SafeSearch, and a clickable list of the URLs in the naughty array if the number of URLs in the naughty array is less than ten.)
