OT: there is a 'dead' comment by a user going under the handle gazelle21 [1] at the same level as this comment which seems to have been insta-killed which most likely means this user has been shadowbanned. The actual comment does not merit killing as it is related to the subject of this discussion and does not contain anything 'sensitive' or 'triggering' unless the sensitivity levels have been turned up higher. Going through this user's comment history I notice that most of the comments and al the submissions - going back to 2019 - are 'dead' but - and this is the odd thing - some are alive. I did not see any warning from dang to this user that he was about to be banned if he did not change his ways nor did I see any particularly shadowban-worthy comments or submissions. The user's 'karma' level is positive so that is not the reason for the untimely expiration of his comments either. Why was this comment killed? I have been told that shadowbanning is not practised here but can not think of anything else other than this user being watched by a number of particularly vengeful detractors who jump to the down-vote/flag options any time a post or submission appears. The comment itself fits the discussion so that can not be the reason. What is? [1] https://news.ycombinator.com/user?id=gazelle21 https://news.ycombinator.com/user?id=gazelle21
