Ummmmm, hello? Have you recently tried creating an account? There is no way that they can authenticate your real age, it doesn't take a genius to put their birthday as "21st January 1980" or something into their box asking for age. So then 8 year old + half a braincell + a calculator + a friend encouraging him = An account that can turn on and off the filter and they can swear to their little hearts contents. You would honestly see just millions of accounts on F2P GE going "[bleep], [cabbage], [bleep], [bleep], bastard, [bleep], *giggle*" then it's just rinse and repeat. So therefore many of the more adult players (which this would be intended for) would end up having it off being back at square one, with immature little kids swearing their little hearts out. You will only see a bunch of stars if you turn on your filter and you can always just put them on your ignore list. I don't see the problem.
