There are many with subtle tells.

Not nearly as obvious as the ones from 6 months ago, but seems to be more the use of hyperbolic phrasing in a particularly unnatural way.

The assess/explain, then hyperbole at the end kind of structure.

Top comment looks suspicious from this perspective, but it's kind of a losing battle to be able to differentiate them with sufficient accuracy anyway

This is very reminiscent of the "everyone's a Russian bot" era of social media, where everyone would just lob that accusation at people without any real proof.

There is no way to prove, but what is definitely true is that many people are attempting to use LLMs on forums and otherwise.

So if you think none of these comments are written by LLMs, you're probably mistaken too.

In the end we accept that we can't tell anymore and move on (barring some biometric protocol that can't be gamed via automation)
