This is a straight up misrepresentation. The user posts occasionally about Israel, which garners engagement and replies (in some cases from actual trolls who job is searching for mentions of Israel), but most of their top level comments are about mundane technology.
I guarantee that there are zero people paid to search "Israel" on Hacker News.
It's not a misrepresentation: 13 out of their 21 posts are about Israel.
I don't know why you brought comments into it, the most common reading of "posts" is "submissions", not "submissions and comments".
