Exactly. You should hear some of the stuff that comes out of the mouths of under 13's, even under 10's nowadays. I'm only 17, but I never used to dare swear at 10, possibly cos I hardly knew any words to use, and I was nowhere near as cheeky as kids are today. (God, I sound like an old man). But I don't think a swear filter would serve much purpose - with the amount of swearing in society today, it's a wonder if anyone takes offence to it anymore.
