Have you tried treating a /64 in IPv6 in the same way that you'd treat a
/32 in IPv4 (and thusly, a /32 in IPv6 in the same way you'd treat larger
IPv4 blocks targeting bad provider space, etc?) rather than fighting every
/128? This seems to be a pretty common practice that has worked for others
in dealing with abuse issues on IPv6.
