Hmm that's kind off an unexpected reply.
I don't know if this really is about right-left bourgeois direction-politics or a cultural issue.
If you want to fight pederasty you need to fund investigative police-work, like with detectives and crime laboratory stuff. And you need highly trained social workers that can figure out if children are in social conditions that could lead to molestation.
I don't really see the point of bothering with computer and internet stuff, by the time pedophile-porn ends up on the internet it's too late and the damage has been done.
If you find the pedos in meat-space that will fix the internet content problem by extension.
If this really is about protecting children online, then i would be onboard with a general ban to post pictures of non-adults online. Because that makes it a privacy argument. You can argue that children can't consent to their likeness being published, because they aren't legally able to consent. Parents arguably don't have that right either because it might have effects beyond childhood and that would be violating the privacy rights of future legal adults.
The big advantage of a general age restriction mechanism is that there is no need to have a data-base full of CP to create anti-CP-filters. And you won't end up with government institutions or private corporations that are filled with pedophiles ""managing the illegal content containment"". You can have a relatively simple algorithm that is very accurate at guessing the age of somebody even when photos don't include a face. There's no need to do any invasive stuff like hack into the phones and computers of private persons either. And the age-guessing algorithm has no legally problematic technical components derived from CP, so it can be opensource code that can be inspected to make sure there are no malicious features. It's also very light on computation resources, cheap compact-cameras with 500mhz MIPS-architecture processors could do this a decade ago. You can add this to any website or app without it becoming a regulation that promotes big tech-monopolies because only they are able to have the technical and legal capacity to implement it.
I don't believe for a second that the people who have proposed the CP-scanner laws care about protecting children, because they want to undermine the privacy anPost too long. Click here to view the full text.
