If you use virtual private networks, or VPNs, to conceal your identity while surfing the Internet, you may be a little steamed at Hulu’s decision to block anyone attempting to use their site while connected to the Web via a VPN. Hulu has begun employing the practice this week, TorrentFreak reports. Hulu is reportedly blocking the use of VPNs because a large amount of people outside of the U.S. have allegedly been using them to connect to and use the streaming site via an IP address based here in the states.
