Correction, on further inspection the mahara.org forum is already
checking for blacklisted domains in forum posts. And it appears to work,
because the only spam that's getting through has domains that aren't in
the spamhaus blocklist.

We aren't applying the other anti-spam measures, like making sure
there's a limited number of URLs in the post. But most of our spam only
has 2 or 3 domains per message, and it's possible to spam just as
annoyingly with only one URL.

So it would appear our one remaining option is Bayesian filtering.

Title:
  mahara.org forum spam

Status in Mahara ePortfolio:
  Confirmed

Bug description:
  Mahara gets a steady annoying flow of forum spam. On a typical day
  it's 5 to 10 messages. This isn't a whole lot, but since the number of
  messages on mahara.org's forums is fairly low, this makes up about 40%
  of the messages each day.

  I'm opening this bug to explore options to deal with this issue.
