Blocking of particular domains using privacy lists is unlikely to work as 
spammers just buy new domain names every few days, just like they do today 
with email spam, same with blocking IPs, if spammers realise they are 
getting blocked by IP they will just start using their bot networks to 
provide a virtually unlimited supply of sacrificial IPs to use.

Message filtering at the client might partly work, but it wont help with 
bandwidth wastage between the client and server or the server to server 
traffic.

To solve the spam problem we need to develop some kind of system that works 
at the s2s level like just like dialback does, either some kind of server 
level message filtering (aka spamassassin), or some kind of web of trust or 
RBL system to identify rogue servers.
