It's probably because of HN's anti-LLM filter. I don't know if submitters use LLMs to touch up their descriptions or if these descriptions often use LLM-like phrasing.
If that's what happened, I wonder if the same filters exist for tools like Grammarly. Some people are English as a second language, and some people simply want to put the best foot forward and make the best first impression.
