A bug? Really?
If so, it seems like a very specific sort of feat- uh, error. One that happens to add to a building vocabulary, so my thanks to whoever pointed out that new bit of censorship.
However, if those responsible for the platform that displayed that censorship actually are taking steps to remedy that feat- uh, error... they'll be a step ahead of 微软. As it is, it's certainly a peculiar kind of fuel.
If this doesn't get a body on its feet and on guard, I don't know what will.
