Interesting scenes on Twitter, which appears to have implemented a block on users clicking on links to filesharing service KickassTorrents. As TorrentFreak reports (and we’ve tested this morning) clicking on a link to the torrent site brings up a warning page: “The site you were trying to visit may be unsafe! This link has been flagged as potentially harmful” with users able to click a button to learn more, another to go back to Twitter, but no option to continue to the link anyway. Twitter has yet to comment publicly on its decision to block users from visiting one of the world’s most popular torrent sites. Rightsholders in the various creative industries will be pleased by the news – KickassTorrents is a regular in listings of notorious piracy sites – although some internet campaigners will be sure to protest on the grounds that *some* files on its torrent index aren’t infringing copyright. Whichever camp you fall into, it would be a good thing if Twitter were to explain why it’s blocking this particular site, and whether it plans to extend the policy to other torrent indexes too.
