That looks like a 1918 issue to me... Lets be clear about the difference 
between a DNS query for 1918 space and a DNS query sources from 1918 space 
which can never be returned too.

Yes I'm sure it is annoying, but the questions are:

How much EXTRA load does it really place on the rootservers?
Is it really so much load that you can't just chalk it up to a normal 
part of the service being provided?

Or to put it another way:

How much computing power would I need to buy you so that I never have to 
hear complaints about queries from 1918 space on a mailing list again? :)
