It's obviously says LLM to me at first read through.
I suspect that:
a) less people are willing to expend a bit of energy to notice LLM usage given how much of it is. ("we've lost" theory)
b) that people are losing the ability to detect LLM submissions. ("we're cooked" theory)
or c) that people don't care about the use of LLM. ("who cares" theory).
Personally I've been feeling less invested, because it seems as if most users don't care and even the main users of the site don't notice it.
