Move the site to TOR and let digital copyright enforcement cops try to figure that one out. All they can do it push it completely underground and once the site is on TOR they have zero recourse or means to track down the operator.
The site is just text transmission, like torrents. Your connection to the news server would not have to be piped over Tor, just your access to the web interface where you download text files telling your news client what to download.
