There is an on-going tabloid newspaper campaign where they are trying to force the ISPs and politicians (especially the opposition) to adopt or commit to an "opt-in" for porn on Internet connections. That is, the default would be required that ISPs take on the cost and legal culpability to block porn.
It's the same as what my mobile network (O2) do as well, I tried to read a news article to do with poker, and I got a "This content is rated as over-18. Please call us to have it unblocked" (paraphrased - as I can't remember precisely what it said)
If it's the same as what Vodafone does with their content control, then let me assure you it's completely broken. With the filter turned on, I can access any porn site I tried, but some articles - I couldn't.
