Apologies for the interruption of service. Google's anti-spam bots decided that this blog was spam.
Google's bots can of course have type I and type II error; if they're on the frontier, they can only trade off killing real blogs against failing to kill spam blogs. I would have thought, though, that an efficient algorithm would weigh at least somewhat a site's Google PageRank. Offsetting is PR6: one below the University of Canterbury's main site (PR7). If a spam blog can get to 6, then something's wrong with PageRank.
We now resume our regularly scheduled service. I hope to pass my future Turing tests.
