Some Chinese websites offer GENUINE copyrighted materials downloading/streaming for free (i.e: these websites signed some contract with the copyright owners and could legally distribute copyrighted stuff only in China) . I'm in U.S, and use a VPN server in China to bypass the IP address restriction imposed by those sites to download/watch those TV shows& music for free(for my personal use). I know it violates term of the serve of the sites and they have the rights to terminate their service to me (I don't pay for it any way). Is my action legal in U.S? Could copyright owner or Chinese sites sue me?
