So you assumed everyone else would be able to catch the specific comment you read in a forum thread that will shift comment positions, or allow users to delete them.
There was no malice intended. At the time I commented, also the top comment here in HN was saying the same thing. So I assumed everyone knew what we were talking about. This whole HN thread had like 10 comments in total so it was easy to read. Then the thread made it to the HN front page, and it blew up. (And people in the US/Europe woke up while I was having dinner with friends here in Australia).
Edit: the HN comment I’m talking about is this one, you can see from the timestamp it's older than mine https://news.ycombinator.com/item?id=21104074
