[Original research here!]
I ran a copy of the relevant censorware and found why Boing Boing got censorware'd by Boston Municipal Wi-Fi.
Remember: "The phrase "Banned combination phrase found" is a characteristic message of the censorware Dan's Guardian. http://www.dansguardian.org/ It seems some combination of words has triggered the "isItNaughty" flag (that's what they call it).
This is the message that appeared in the server log:
http://www.boingboing.net *DENIED* Banned combination phrase found: google, &safe=off
It looks like the "Banned combination phrase" was the following link, because of the search with SafeSearch set to "off":
Much more of Biskup on Boing Boing <a href="http://www.google.com/search?hl=en&safe=off&domains=boingboing.net&q=%22Tim+Biskup%22&btnG=Search&sitesearch=boingboing.net">Link</a>
"Arbitrary and capricious" seems the relevant characterization.
[Update: BoingBoing should be viewable again on that network when the offending post scrolls off the main page, which should happen in a day or so. But that post itself will remain censorware'd until someone changes the phrase blacklist entries]
