Netflix might not mind if you share your account with a friend, but when it comes to watching content that shouldn't be available in your country, it's not so forgiving.
The practice is pretty widespread. Using a VPN (virtual private network), you can fool Netflix into thinking you're based in America, and hence access Netflix US's much bigger library of TV shows and films. Though it's a legal grey area, so we wouldn't advise doing so.
While Netflix has previously turned a blind eye to the practice, now it's clamping down. It'll take steps to stop punters streaming content that shouldn't be available in their country.
"In the coming weeks, those using proxies and unblocks will only be able to access the service in the country where they currently are," David Fullagar, vice president of content delivery architecture at Netflix, wrote in a blog post.
Netflix's catalogue differs region to region because of content licensing deals. Here in the UK, for example, we can't watch 'The Walking Dead' on Netflix. Instead, you'll have to watch it on Fox HD.
Fullagar added that Netflix hoped to one day offer the same content in all territories, but at the moment that wasn't possible.
Netflix recently announced it had come to 130 new countries, meaning it's now available in 190 countries around the world.
