This fool also doesn't seem to understand that it's all about
relative effort; the Internet is so chock-full of soft targets
it is hardly worth an adversary's time to search non-default
ports, but a lot of systems change the default simply because
they're tired of their logs being choked by random bot scanning
for known vulnerabilities.
