Concur - but it seems that many seem to be looking for someone else to do this for them (or, perhaps, the lack of someone to do it for them as an excuse to do nothing at all).

How much of a problem is traffic from unallocated addresses? Backbone operators probably have NetFlow data which they could mine to find out.
On the other hand, how much of a problem is obsolete bogon filters causing
everytime IANA delegates another block to an RIR?

Or by the way, how much spoofed traffic uses allocated addresses?
