[Speaking as a user] Yeah, it looks inorganic for me too. As another user said the gold trim signals that the post was gilded, gilding nowadays works like a "mega-upvote" and gives it that trim. It's possible that defenders of the Jewish genocide (Holocaust) and of the Palestinian genocide (the ongoing war) are dumping money in those posts, to promote their shitty discourses.

And that works really well in Reddit because the userbase there loves some oversimplification: they have a really hard time decoupling the Jewish people from the State of Israel.
