I don't see a problem with this.
If you wish to have that sort of imagery then you need to have the filter changed.
I can't quite tell if that would be something you could do personally, or if you need to contact your ISP to do it though.
The only real problems I can see happening is certain websites may be blocked which some could recognise as researchographic, despite not being so.
There are websites dedicated to Art that depict the naked form, in such things as paintings and statuary.
It does leave the question of what point the Government deems something as researchographic or not though.
For example, "LotsOfTits" dot com is probably researchographic (or a keen avian fan site).
Nuts Magazines website however features the same sort of images that are in Nuts Magazine, which are naked or scantily clad women, but often doesn't show nipples, or at the most part, definitely doesn't show genitals.
Seeing as how those sorts of Magazines are allowed in magazine racks in Supermarkets and Newsagents, with 90% naked girls on the cover, where Children could easily spot the image, it wouldn't be fair if the websites for companies like those require people to have to manually change whether they can access them.
Not everyone is tech savvy and might not understand how to go about gaining access to those websites, and that would result in a loss of money to those companies.
Which ultimately means a loss of Tax for the government.
But other than that though, there's nothing wrong with them putting more measures (even if they're very basic) to stopping people watching research.
And there is nothing wrong with them putting in measures to try and crack down on Child research and it's viewers, as well as stopping Rape Material being readily accessed online.
