It's likely getting flagged organically (and due to the ratio of comments to upvotes, getting penalized by the flame war detector), but not due to a vast YC conspiracy.

Hm? You and I agree. There’s no conspiracy here. This is "bog standard moderation", as Dan would say.
Look at it this way: if the community didn’t flag it, it would be the mods’ duty to get this one off the front page. So whether it was the community or the mods is incidental.
