Moderating something like HN is a very hard job. Gratitude .
EDIT: unfortunately I cannot defend my point in the comments, as I am now rate limited :)
EDIT 2: /u/Dylan16807 yes I'm seeing that. When I try and post it says "you are posting too quickly, please slow down"
I think shadowbanning is a bit unethical as it technically involves lying, but afaik HN doesn't do such things.
It does. A ban on HN is a shadowban. You can still post but only those who have "show dead" on will see it (greyed out and marked dead).
