More than half (54 per cent) said they don't use the porn filters, and 22 per cent don't know.
The respondents who opted against the filters did so mainly because they didn't want their internet access "hindered in any way," although some also expressed concerns over censorship. A few said they used their own filters.
On the other side, porn filter enthusiasts largely said they wanted to protect their family, while the rest just didn't care to see such content.

Now the Broadband Genie survey isn't especially reliable, with a small sample size and questionable method, but it does suggest that the British people aren't exactly convinced by Cameron's porn policing policy.
As pointed out by Arstechnica, these figures represent the first bit of data collected on the second phase of the project, in which internet providers make porn blockers default — meaning that new subscribers have to 'opt-out' rather than 'opt-in'.
In February this year, all the major providers had made the porn filters default.
Although the vast majority of Britons continue to shun the scheme, this data reveals that the change in policy has led to a massive increase in the number of people using porn filters.
An Ofcom survey last year found only a small number of people had volunteered to use the filter — 4 per cent of Virgin Media customers, 5 per cent of BT subscribers, 8 per cent Sky users.
The Conservatives will likely continue to pursue this course, committing in their election manifesto to "stopping children's exposure to harmful sexualised content online, by requiring age verification for access to all sites containing pornographic material and age-rating for all music videos."
