Say eyeball provider X has implemented automated S/RTBH, and I have a
grudge against them.
I would simply DoS a couple of the subscribers *with spoofed source IP*
addresses from google, youtube, netflow and hulu.
The automated S/RTBH drops all packets coming from those IP addresses.
Presto; many angry consumers call the ISP's helpdesk.

Comes back to providers allowing "spoofed" traffic into their networks from customers.  That seems to me to be the 
low-hanging fruit here.
