(I do find it interesting, btw, that a few seconds after post this did get an immediate downvote to 0 - it didn't last, but it makes me wonder if there are bots monitoring the HN firehose for anything critical of country X)

There are easier explanations. A hundred people are checking and occasionally the page, with new posts added every couple of minutes: clearly some will meet a post at "0 minutes", read it as fresh, and possibly react. I have seen it.
Possible, certainly. On the one hand the HN audience is not very big in the grand scheme of things, but they probably do skew to more influential and likely to be politically active than the average person. If it's worth doing, it's almost certainly being done.
