A start would be blocking 2620:108:700f::/64 as discovered by a simple 
DNS lookup on netflix.com. I am not running a HE tunnel (I got native 
IPv6) and I am not blocked from accessing Netflix over IPv6 so can't 
really try it. I am curious however that none of the vocal HE tunnel 
users here appears to have tried even simple counter measures such as a 
simple firewall rule to drop traffic to that one /64 prefix.

It might be that more needs to be blocked, but in that case it will be 
trivial to find the required prefixes by launching Wireshark and observe 
the IPv6 traffic generated when accessing netflix.com. Maybe someone 
could do that and post the results, as it is apparent that many people 
are in need of a solution.
