And how many people do you think use these 3 lnks compared to the base URL? That's the clever little ways to censor. You don't need everyone to be unaware, just as many as possible.
That's why I tend to search top in the last day and week. Specifically to catch flagged articles like this, since at least the votes don't get undone.
Please, the topic in question is whether HN "is one of the biggest culprits" in "adopting Chinese censorship methods". Granted, I'm far from being knowledgeable in Chinese censorship methods, but I doubt they can be circumvented by just using different URIs.
I don't agree with that because HN is a relatively small site. But the methods used here aren't dissimilar to what is happening in this story nor in China. Burying stories is a big part of censorship while minimizing dissent.
