You've got to know where the review takes place as well. I'd be fairly confident it remained in China and not the U.S., and this is just another example of what may happen when doing business in China. I know that the cool thing to do is vilify Microsoft, but I think they are part victim here. Now that corporate is aware of the issue, they are working to resolve it. Plurk should be happy for the publicity they received out of this (I'm sure they were high-fiving around the office when it was discovered).
