Making an inflammatory claim and calling it "obvious" guarantees the kind of thread we don't want on HN. That amounts to trolling. Please don't do it, and please don't stoke flamewars once they get going, either.
Accusations of astroturfing or shilling without evidence are not allowed on HN. Rushing to that as an explanation is, invariably, evidence of sloppy thinking—or maybe non-thinking, of the kind that political passion leads us all to. It should have been obvious that there are many countries where people were reading HN at that hour and that you'd given plenty of them plenty of reason to downvote. It's embarrassing to see a comment here insinuate that only Russian spies could possibly disagree, and just as embarrassing to see how many users upvote such an absurdity.
This community is deeply divided on divisive issues. People on all sides need to conduct themselves more civilly than this, so please don't do it again.
