Except that this thread started with a recommendation to block  an entire
AS, containing a reasonable number of networks.

Recommendations such as that are only as credible as the source they are
coming from, and knowing that the person making the request also believes
that blocking all mail from is a valid anti-spam technique
probably results in a "different" credibility level than one might otherwise
