This site now has a PICS label. PICS “was originally designed to help parents and teachers control what children access on the Internet, but it also facilitates other uses for labels, including code signing and privacy.”
I don’t swear much on this site, but it’s nice to be nice and all that. If you want to do the same you can use the ICRA Label Generator and the ICRA Label tester.
Ohh and I’m not pointing any fingers, at anyone I think should do this. Honest.
