Thanks so much for running this site - as a small start-up we often manually request a snapshot of our privacy policy/terms of service/other important announcements whenever we make change to them (if we don't manually request them the re-crawl generally doesn't happen since I guess those pages are very rarely visited, even though they're linked from the main site). It's helped us in a thorny situation where someone tried to claim "it wasn't there when I signed up".

It might be an interesting use-case for you to check out, i.e. keep an eye of those rarely used legal sublinks for smaller companies.
