The "every" claim is correct if you subtract this one exception https://news.ycombinator.com/item?id=22618517 which happens to be the least interesting post that really won't do much help for the company.

And the real question that you still won't answer, how many very young/unknown companies have their posts on the HN's frontpage more than 4 times in less than a month with a 100% hit rate? give me other examples so that we know this is really so natural.
