No it doesn't. That bot's comment and every comment under its profile 100% reads like an LLM to anybody that has seen enough of them. I already knew that one was a bot before even clicking the profile. See enough of them and the uncanny valley feeling immediately pops out. Even the ones that try to trick you by typing in all lowercase.

An em-dash might have been a good indicator when LLMs were first introduced, but that shouldn't be used as a reliable indicator now.

I'm more concerned that they keep fooling everybody on here to the point where people start questioning them and sticking up for them a lot of times.
