The data in sc.surbl.org is also weighted based on number of
reports.  (You and I came up with very similar solutions for
handling the SpamCop data.)

But the WS list source data does not always have this "spam
volume" data behind it.  In some cases, the source data are
just singular lists with no counts of how often they appeared
in spam.  So weighting is probably not available across all of
the WS data.

I agree it's a useful concept though. I think of it as a form
of voting
