I don't want AI companies to scrape my sites (or use the files I wrote) for training data either, but that is not specifically what I am trying to stop (unless the files are supposed to be private and unpublished). I should not stop them from using the files for what they want, once they have them. (I also specifically do not want to block use of lynx, curl, Dillo, etc.) What I want to stop is excessive crawling and scraping of my server. Once they have the file they can do what they want with it. Another comment (44786237) mentions that robots.txt is only for restricting recursive access; I agree and that is what should be blocked. They also should not access the same file several times quickly even though it should be unnecessary to do so, just as much as they should not access all of the files. (If someone wants to make a mirror of the files, there may be other ways, e.g. in case there is a archive file available to download many at once (possibly, in case if the site operator made their own index and then did it this way). If it is a git repository, then it can be cloned.)
