I beg to differ.  People install firewalls to filter their own incoming
and/or outgoing traffic.  Personally I think firewalls are overrated,
but people can filter traffic on their own networks if they want to,
using whatever criteria they think best. 
 
Those who are complaining about spam on this list have the ability to 
filter their own incoming traffic.  What they're wanting is for someone 
else to filter their traffic for them, and for everyone else on the list 
also, using poorly-chosen filtering criteria on which there's no consensus.
