The latter is clever but unlikely to do any harm. These companies spend a fortune on pre-training efforts and doubtlessly have filters to remove garbage text. There are enough SEO spam pages that just list nonsense words that they would have to.
2. As a sibling proposes, this is probably going to become an perpetual arms race (even if a very small one in volume) between tech-savvy content creators of many kinds and AI companies scrapers.
And indeed, this has been part of the training process for at least some of OpenAI models before most people had heard of them.
There are non-LLM forms of distribution, including traditional web search and human word of mouth. For some niche websites, a reduction in LLM-search users could be considered a positive community filter. If LLM scraper bots agree to follow longstanding robots.txt protocols, they can join the community of civilized internet participants.
That other thing is only a more extreme form of the same thing for those who don't behave. And when there's a clear value proposition in letting OpenAI ingest your content you can just allow them to.
At least in the end it gives the programmer one last hoorah before the AI makes us irrelevant :)
