We had a similar issue, though in that case we found:

1.  The user had been sharing the account between 3 different households 
across (a) 2 different IP blocks within our network and (b) with a 3rd user 
on an entirely different ISP in the US (we're in Canada), with multiple 
devices in use by some locations.

2.  The sites across which the same account was being shared had different 
connectivity options, with one of those having a decent chunk of MTU 
overhead on the connection (l2tp + pppoe etc.), perhaps raising some flags 
in Netflix's detection due to smaller MSS?

3.  Using the same account on different IPs on the same provider also got 
blocked.

4.  Using a different account on the *exact same IPs* did not have any 
streaming issues, suggesting Netflix was flagging the account rather than 
(just) the IPs.

Dunno if that helps, but it may be beneficial if Netflix can provide some 
guidance on the logic in the "this is behind a VPN/proxy" detection (though 
I am assuming they likely won't disclose that so as not to give away 
secrets to the other party in the arms race).
