[dns-operations] Effectivity of filter lists against DNS amplification attacks

Lately, there was much discussion and examples on how to block the DNS 
requests of DNS Amplification Attacks. Such filters prevent the name 
server seeing the request, thus of course massively reducing the 
outgoing traffic. But such filters can not reduce the incoming traffic - 
the attacker will still send the DNS requests.

Thus, I would be interested in the results of such filters. Do you see, 
maybe not in short-term but in long-term, that the incoming attack 
traffic also decreases?
