Which is more important, the rights of the infringed or of the funded and hyped business?
Nice product you have there, shame if it got sued for copyright infringement.
Equally, every author should also have the right to not have their work ingested by AI.
However you'd have to delist yourself from search engines to fully prevent AIs from reading the content on your website.
It most certainly does not. robots.txt is almost totally worthless against genAI crawlers. Even being unindexed from search engines doesn't keep you safe.
There's ample documentation of crawlers straight-up ignoring robots.txt.
It's not a legal control, but a technical one - and a voluntary one, which means that it's trivial to ignore.
And there's obviously nowhere to put a robots.txt for a book that you've published.
