Well, duh...

Tech giants 'could stop child porn online if they wanted to', says chief of National Crime Agency is the headline in this Telegraph article, the majority of which is behind a paywall. But I think we get the gist of it with what we can see: https://www.telegraph.co.uk/news/2018/09/30/tech-firms-must-do-tackle-rise-ofchild-abuse-images-shared-online/

Tech firms could end the proliferation of indecent images of children online instead of tolerating it, the National Crime Agency (NCA) chief leading the fight against child abuse has said.

Rob Jones said the firms had the technology to be more proactive to prevent images reaching the web in the first place to stop crime happening and to hunt down paedophiles grooming children.

In an interview with The Telegraph, he warned their approach was too reactive and there was a danger of online child abuse being normalised in society by the continued proliferation of thousands of images that were too easy to access on the “open” web.

Well Rob, that's what we've been asking for years now on these forums.
