Earlier today, I did a search for the circus performer David O'Mer, using his stage name 'bath boy' and was horrified to get a page full of images of naked children in bathtubs on Google. I hindsight, I should have added his name to the search!!
I guess that some images of bodies are useful for medical students, etc, but I do worry that it is so easy for people to access large numbers of images of completely nude children. I had a look around Google's support pages and their attitude seems to be 'we just show what's out there, if you don't like something, contact the website owner' and they only seem concerned about images of sexual activity with kids. You can't complain about a whole category of images, only specific ones, so I couldn't submit a complaint to Google about this, and would imagine they would just reject it if I did.
It's a difficult one as excessive censorship can be counter productive and criminalise reasonable activity, but it just doesn't seem right that you can be presented by a mass of images of naked children so easily, even when you aren't even seeking these!
Would be interested to hear the thoughts of others on this.
