> Telesign, a company that advertises fraud-prevention services for businesses, offers a simple form for “Data Deletion” and “Opt Out / Do Not Sell”. But that form is hidden from search engines and other automated systems, and isn’t linked on its homepage. > > Instead, consumers must search about 7,000 words into a privacy policy filled with legalese to find a link to the page.

In fact, while they do have a robots.txt [1], their form [2] isn't actually listed there. Instead, the page itself has a meta tag:

    <meta name="robots" content="noindex, nofollow">

(Disclosure: I work on Mozilla Monitor, where we try to help people send these data deletion requests.)
