There are a whole bunch of reasons why this is dumb.
The wording gets vague at points - at what point does whipping become 'aggressive'?
What has female ejaculation even got to do with anything? The rest is all 'violent' stuff and while female anatomy isn't my strong suit that just doesn't seem to fit.
From what I understand it's only porn that was actually made in Britain with these restrictions and a lot of porn isn't so it's somewhat irrelevant anyway, unless they start banning any foreign porn with this stuff in (good luck with that)
Pissing stuff is banned but scat's fine, what
Who the hell even cares what porn people watch
Seeing this kinda stuff doesn't necessarily even mean people will do it (which I'm guessing is why all this stuff was passed, to stop violent sex crimes and the like), hell if anything when it's well-produced the videos will be showcasing how to do fetishy stuff like this safely.
I'd lost track of what happened to that whole situation a while back with British ISPs being forced to ban certain sites, it was pretty worrying at the time because government censorship is a scary thing, and this looks to be something along those lines.
