Erm... Hong Kong is more or less a separate political entity. Not that we are political at all. Well, we do have freedom of speech, although it's often encroached on in insidious ways, like the pandering of the commercial media to the Chinese government, exacerbated by the lack of an independent public TV station like the BBC to balance it.

It's not just LJ they block. A Chinese-language SPN site I frequent is also blocked. But Chinese fans are ingenious with computers, it seems, as they just use proxies to access them. BTW, Ultrasurf (the software I used to access those US-only web sites, such Heroes episode commentaries) is also invented by Chinese.
