Just out of curiousity, under what circumstances do comments completely disappear from HN threads? I recently posted a comment (this thread:
https://news.ycombinator.com/item?id=34116509 )that several people found offensive to the HN culture and rules. Some comments called me out for my word choice, or the sentiment I expressed. Some agreed. In two or three cases, where I responded to criticism with an explanation of my intent and and apology for the unintended offense, and one where I simply agreed with the interlocutor, the comments - both my response and the one I was responding are now gone. How does this happen?
And sometimes threads of comments are "folded", and can only be viewed if you click the "X more" link to the right of the header. But I don't think they are usually removed completely.
I'm guessing you are referring to your comments in this thread: https://news.ycombinator.com/item?id=34116509? If so, the comments you are looking for are probably under the two "folded" threads at the bottom.
