The site, Immunicity.org, offers a proxy server and a proxy autoconfiguration file (PAC) to tell browsers to access various blocked sites (PirateBay, KickassTorrents et al) via the proxy.
The Police Intellectual Property Crime Unit has arrested a 20-year-old man in Nottingham on suspicion of copyright infringement for running a proxy server providing access to other sites subject to legal blocking orders.Is operating a proxy server illegal? Interesting. Seems unlikely that this will go to court though. (Via TJ McIntyre)
