There could be some methods they can employ, but I don't see any of them being remotely foolproof. E.g. if they ask NYT to provide them with a list of content hashes to check against or the content itself to match similarity, but it's really easy for plagiarisers to use already existing open source LLMs to slightly modify content in different places in automatic fashion. And they would be incentivised to do that as well. I don't see right now how this battle could be won in theory. There's going to be bunch of content farms, plagiarisers using their open source LLM automation tools, which essentially launder the information from other sources. Even if you denylist them, it's arbitrary for them to spawn further instances. Eventually the only way would be to not use the Internet at all, and only use allowlisted sources. But that's quite ridiculous to me.
