This issue is largely manifesting through AI scraping right now. Additionally, many intentionally ignore robots.txt. Currently, LLM scrapers are basically just bad actors on the internet.

Effectively, if you don't like the status quo, stuff like this is one of your few options.

This isn't even mentioning of course whether we actually want these companies to improve their models before resolving the problems of energy consumption and potential displacement of human workers.
