I keep hearing people say this, but I've not seen any clear  
justification for it. It seems to me to be no more difficult to run a  
blacklist for IPv6 addresses than IPv4 addresses (neither is easy, but  
the details of the address representation don't seem to make more than  
minor differences).

Can you expand on why you think it's the case, or point me at some  
discussion of it?

Cheers,
