There is no legal protection for you because internet systems have reserved rights to block certain downloading pages due to copyright violations. Installing a VPN is the only way to bypass these limitations. Since it works just for a little time, you should even try location spoofing. Alternatively, to reach the pirate bay, you should use mirror pages. These pages duplicate the content contained on the main site, making it easy to share torrent files even though you are unable to access tpb on your own. But you should carefully pick your pirate proxy sites since others are already on the authentic radar.
