I don't recall any instances where I've run into the problem here, maybe because I tend to arrive to threads as a result of them being popular (listed on Google News) which means I'm only going to read the top 10-50 posts. I read human responses for a bit before deciding if I should continue reading, and that's the same system I use for LLMs because sometimes I can't tell just by the formatting; if it's good, it's good - if it's bad, it's bad -- I don't care if a chicken with syphilis wrote it.
