Somehow this article is no longer on the first page[0] (or even second) of hn even though it has more upvotes (and is newer) than other articles with less upvotes (or older ones). Is HN hiding politically controversial articles?
They fall off the main page when people start flagging. If enough people flag it will instead be [flagged]. For a period of time it can get vouched if [flagged] and then [flagged][dead].
