But don't find yourself actually needing to get in touch with a human there. I have a friend that inadvertently doxxed themself on a website they own; they removed the pages, added a robots.txt to disallow crawling and is trying for months to reach someone over there to just get that data removed from The Wayback Machine, to no avail.
Perhaps archive.org doesn't have a lot of staff or they simply don't care but I imagine these kinds of things happen often enough that they should at least have an automated process in place (and continuing to crawl a website that specifically forbids it through the standard robots.txt is a bit icky).
