On a more serious note, almost all children swear from a fairly early age, often before they even know what the words mean.
Many adults swear.
It is only that the two seldom do so in the company of the other that makes there be this prevention of swearing in front of children (and prevention of kids swearing in front of adults). When with peers the "language" flows.
IIRC kids are often 13 and above when on this site, I bet if you listen to almost all of them in real life you will hear them swear.
Should we stop swearing in front of kids because we don't think they should swear even though they do? I am not so sure, especially with acronyms. Overuse of swearing just makes the word less explicit and less shock creating.
My child is 7 and does not know any swear words. We don't swear at home and he has not heard any bad language at school either.
I don't think that it is appropriate to have swearing on a website about a hobby which attracts quite a number of young people. And I think we've already proved that there are a number of under 10s looking at the site.
I agree with the poster who said that kids copy adults. Of course they do, that's how they learn.
