Netflix is clamping down on users accessing the service through a VPN, with its updated terms of service threatening to "terminate or restrict your use of our service, without compensation or notice".
Virtual private networks are used for a variety of reasons, but with regards to Netflix usually to combat limited download speeds and access content restricted to other territories.
Here's the key clauses:
You may view a movie or TV show through the Netflix service primarily within the country in which you have established your account and only in geographic locations where we offer our service and have licensed such movie or TV show. The content that may be available to watch will vary by geographic location. Netflix will use technologies to verify your geographic location.
The update was spotted by Reddit user CrypticCraig, who claims a Netflix customer service rep confirmed in Chat that "Netflix opposes the use of VPNs".
Netflix is pretty forward-thinking with regards to internet piracy, so I wouldn't expect them to start charging around banning users however.
Last week, its CEO promised to reduce the need for proxy and VPN workarounds by announcing plans to make its content global.
