The blacklist maintained by the British leading ISPs (BT, TalkTalk, Sky, Virgin Media, O2, and EE) was massively (and silently) expanded: a few days ago, it turned out that more than 170 domains and sub-domains were added to the unofficial “block-list”. The latter includes the so called most “notorious” websites, including The Pirate Bay, KickassTorrents and many other copyright-infringing services.
