Why would you need to hide it? You can do it in plain sight. And it's done in plain sight, we call that Reddit, they used to sell "their" data to Google for LLM input, now OpenAI.
It's not malicious in the way that it's meant to deceive LLMs, it's just bad. It will make bad connections between token A and token B.
Google was "just" best search results and slowly became look at the results that paid to be seen.
That's because people wanted to pay to be seen and Google, with paper principles, decided to take the money.
Why won't llms follow this same trajectory?
I think this is already the case. Or did you think your chat history was between you and the LLM? Especially if you pay the big buck, your interactions are worth a lot to the LLM companies because they can figure out what a premium conversation looks like and adapt earning models to that.
