Well, why not? Jagex could try censoring noob for a week or two and see what happens. I think they already did it once, but it was an error, only lasted for 2-3 days. If they censor noob, they'll have to censor all the other ways to say it. You know, it might work. If the jerks can't resist and use any other insult, they will get reported and get banned like they deserve. In other words, be polite or get banned. The fact people can say noob and get away with it makes all the jerks happy.
