Could you elaborate a bit on what you mean by "meaningful"? As 
someone who uses the DUL list as an anti-spam mechanism and who 
experiments with turning it off and on, I can definitely say that 
turning it on reduces the amount of spam I receive (on the order of 
about 100 messages a day).

I recognize that it also harms folks like you for many of the reasons 
you give. But I don't understand why you say it is not a meaningful 
anti-spam mechanism.
