I tested on a pretty normal website and was greeted by this warning: "You must subscribe to surf this kind of content! Note, we block pornography. You must subscribe to surf. ".
thanks for reporting -- i've weakened the javascript a bit on that front. what site did you visit?
You seem to simply be scanning the DOM for keywords. The first site I happened to try contained the word "gay" in one of the headlines, and surely enough http://wikipedia.org/wiki/Gay is also blocked. Doing this on the client side through javascript seems hopeless btw.
