Sounds like they don't want any hits anymore. Meanwhile, alternatives like the Piratebay, isohunt & torrentreator are likely beefing up their infrastructure to accomodate the increase in traffic.
There has been speculation on dutch tech sites that they only did this to appease the dutch copyright vigilantes, so they are making a half-assed effort to filter some stuff out. Let's face it, a torrent site without any "illegal" (under dutch law, downloading music & movies is LEGAL!) content is about as useful as a 3-legged, dead dog. With a nasty case of fleas.
