The Register is reporting on the moves in Scotland which mirror recent law changes in England on what the state defines as "extreme pornography". Basically, like the appalingly bad law introducesd in England it will be illegal to own images of people engaging in consensual perversions if it is apparent harm might be there.
So, a loony guy who gets kicks out of having his scrotum stepped on by a woman in stillettos is out - trust me, these people are out there, I've been online a long time. Likewise, if a group of people have consensual sex but do so by photographing it and playing out a rape fantasy it will be illegal to own them - unless it was you doing it.
Like with alcohol this is yet more puritanicalism that infringes on the rights of the individual to be a colossal pervert in the comfort of his or her own home and look at pornography produced by other colossal perverts for their delight.
Additionally, in Scotland, they have also extended their law so that images of people committing sexual acts with an "animal carcass" are illegal. As the Register points out, they don't really define what an animal carcass is, so technically that might include a 100% beef burger, or perhaps a rolled up steak - apologies if you now need to bleach your mind.

UPDATE: It has suddenly occured to me that if one owned the infamous clip of Rebecca Loos incident aiding a pig with its reproductive duties would that constitue extreme porn if the viewer enjoyed it?
