The 9th comment is explicitly described as "bad results"; it's about somebody who doesn't have a redirect. So that for me is in the "unreasonable" category.

The 3rd is about pool.ntp.org, which is a random ntp server, and which shouldn't be serving up web content. They did happen to pick www.pool.ntp.org as the URL for the docs on the NTP Pool Project, but if "www" never was a thing, the would have happily picked something else. E.g. poolproject.ntp.org or ntp.org/pool/ would have been fine.
