In November 2009, MSN China launched an Internet application called MSN Juku in beta. Commentators described it as a "Twitter-style" microblogging service, although MSN China rejects that description. From the beginning, observers noted similarity between the MSN Juku user interface and that of established microblogging service Plurk, which was blocked in China in April 2009.
On December 14, 2009, the official Plurk blog posted an accusation that MSN China plagiarized about 80% of Plurk's original code, as well as elements of their CSS and unique user interface features. Microsoft stated in a press release that it looked into the accusations. The next day, Microsoft confirmed that MSN Juku (which, it stated, had been developed by a Chinese contractor) did contain copied code, and stated that the service would be indefinitely suspended.
