Re: That's enough @Dave 15
Porn is hugely different on the Internet than in H&E, Fiesta, Club or Playboy. Legal magazines were not able to show explicit sex, and the pornography laws were so poorly defined that mainstream magazines kept well to the safer side of what was acceptable. Moving images add a lot to the impact of porn, and many of the free sites do nothing other than asking that you don't enter if you are under the legal age in your juristiction. With magazine still photos, and story pages, you had to use imagination, which was (in my day) often just guesswork for virgin teenagers. Nothing is left to the imagination on the Internet.
Secondly, it is easy to find porn, even with quite innocent words, and very easy indeed if you really do want to find it. I grant that is has become less frequent that google returns such results than it used to be, but just think how many ordinary words have alternate meanings.
There was a time when a site could 'seed' their pages with lists of completely innocent words, normally in white-on-white and in very small characters, just to try to get random hits. Many years ago, I remember my daughter searching for "medieval castles", and getting hits from some quite unplesent sites. I think that problem has largely gone away now, though.
I do not agree with restricting the Internet by default, but I can see how horrifying it can be to some people.
