pornography have the responsibility to be considerate of those who
don't.
If you are posting pornographic or erotic material, it's your responsibility to make sure no one stumbles on it by accident. First of all, post it in
the right place -- that is, in an area that is clearly marked as containing
material of a sexual nature. Never post pornography or erotica to an
area of cyberspace that is frequented by children. And never post material just for the purpose of being offensive, unless you're posting it to
an area that exists for the purpose of being offensive (alt.tasteless, for
example).
