Yes - however, this is going to be destination-based blackholing, in which one 
is essentially completing the DDoS for the attacker.

There's value in that, however, as the concept of partial service recovery is a

Sadly, it all too often requires little in the way of bandwidth, throughput, 
strategy, thought, or intrigue to effectively DDoS many sites/properties, due 
to poor design and non-adherence to even the most basic principles of 
resilience and availability:
