That one stuck around because the perception that it corrects (of HN moderation being against $COUNTRY, where $COUNTRY = China in this case) shows up semi-regularly—as does the opposite perception, of course. These things always come in opposing pairs.
As a side note, it's interesting to see how different users react to reading such a set of comments, i.e. comments that contradict their assumptions about how HN is moderated. In some cases the reaction is something like, "Wow, I had no idea - thanks for the information" and the person presumably goes on to adjust their priors. In other cases the reaction is a complex explanation of how none of that matters and the original perception remains intact, even though it's inaccurate.
