Since last year, UK ISPs have been required to block user access to the Pirate Bay, for whatever good that has done. The website simply set up a new suite of IP addresses for blocked users, quickly allowing most users to bypass the blockade. Now at least one ISP, Sky, is going above and beyond the initial order and has taken to blocking access to the proxy websites being used to skirt the filters. "I find the blocks to be a bold move since there are so many proxy sites and workarounds out there," insists the operator of Pirate Proxy, one of the larger websites. "If they do continue blocking proxy sites, it will be a cat and mouse game on a large scale," he says. Said mice have already set up a website letting users know which proxy sites are being filtered.
