As the other replies allude to, it worked at one stage.

This subjective and lovely history of the Great Firewall of the PRC was posted recently, about the to and fros in the methods of this kind of thing, and is really very good, if you're interested:

Easily blockable. The early days of getting around Netflix was just using a commercial VPN. Then they blocked all those.

Then we transitioned to a VPS and hosting our own VPN.. then they blocked all VPS IP ranges.

What came next was VPNs that were using other people's home connections (either willingly or otherwise)

Where is your VPN hosted? A lot of sites will block vps hosts.
