That's true.  It's good to hear it's not a bug in the masses scripts, anyway ;)

Yes, I agree, it's actually done a (surprisingly) good job with those.

cool.

In particular, some of the DNSBLs and most of the DNSWLs are good to 'lock
down', I feel, as users tend to 'compensate' or correct their scores more
frequently than other rules -- in my opinion.  Also, if those are given low
scores by the GA, their operators tend to be annoyed, and it's not good to
annoy people who we're relying on ;)

It also reflects that those rules are slightly different, and hopefully 
more reliable, than a typical body rule for example -- there's no way to
indicate this to the GA yet, so locking the rules is as good as we can do.
