protecting kids is the right thing to do.
the reason COPA is back in the news is because the majority of adult webmasters do not do the simple and responsible thing like listing your sites with ICRA.
make it easy for people who do not want to see smut.
list your sites with ICRA.

and, there are some side benefits.
no one can ever say you used a misleading domain to lure kids to your site.
kids can't buy anything from you anyway, so don't waste the BW on them.
be responsible, be proactive.
