Only to notice that this comment never appears at all, it organically was there for a moment and then it was permanent gone and any try to post is just silently does nothing...
Well the comment was pretty long, so I guess HN might silently remove to long comments to prevent spam or similar?
EDIT: The solution was I'm stupid and there is a easy to overlook More button at the bottom of the page. Supper embarrassing. Thanks for the answers.
So HN silently eating such a comment as a form of spam protections seems reasonable, I just wonder if that really is the case or some unlucky network error or similar got in the way.
