Seems like HN is doing something to combat this, considering how many [dead] comments I see in every post (which you can enable by setting `showdead` in your user profile).
I've only recently enabled it so I don't know how frequent dead comments were before the LLM era.
To be fair, I've been here for like 15 years and have had show dead on for most of it, and although the quality of them has certainly gotten lower, I'm not convinced that they are more frequent.
