>It's not reasonable to expect content aggregators/platforms to be able to conduct provenance investigations on all content.

Why? It's content they have no license for right on their servers. It's a purely political decision for providing safe harbor. But there could be made legal arguments for doing not.

Then make those arguments. Don't just say you can. HN is a much more interesting place if you do!

But as for why most of those legal arguments don't make sense: what you're suggesting is that if I defraud you, you're now partially liable for the damages from that fraud to third parties, even though you're one of the injured parties.

That's not how our legal system works.
