Censoring the Net

I've always had an issue with censorship in the Internet. Now my issue became a practical problem. I'm currently at Dubai, and wanted to see how the Finnish health care union salary debate proceeds. However, someone in Dubai thought it's in my best interests to not see that page (what "information security"?). The image below shows how I was caught red-handed:
Now this problem brings me to my issue with a porn-free Internet zone. A really nice idea indeed: who would want to oppose it? However, the problem is: who's going to be the one who decides what is pornography? In Finland people rarely consider a glimpse of breast, as in Botticelli's "The Birth of Venus", offending; but in the U.S. Justice Department the statue "Spirit of Justice" was actually at some point of time covered with drapes. What is more, there are people for whom any portrayal of a woman without a veil or burqa is offending.

So, when designing a porn-free Internet zone, who shall decide what is porn and what is not? Should we aim at creating an Internet which doesn't offend anyone? Or should we vote for a democratic, worldwide majority decision? Or what? Or should we consider particular cases? Vote about particular cases? Text-only Internet (with some words censored)? Does anyone have a really good idea?
