AI search crawlers index pages so that AI answer engines can cite and link to them in their responses. Blocking them removes your pages from those answers, so many sites allow them while blocking training crawlers.
Element451Bot identifies itself with this user agent string:
Element451Bot/1.0 (+https://element451.com)Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
Element451Bot follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
