I've been surprised by the absence of discourse about HK on HN over the past week, given the magnitude of what's going on there and its relevance to this forum's interests. Meanwhile, relatively trivial articles are holding the front page for days.
There is an option for mods to slow or accelerate the decay function of the post.
This is a practice that all content platforms use and few know about. Burying content down, or removing from feed (for Facebook/YouTube) is a soft censoring that avoids user and regulatory backlash.
I would like the platforms to be more transparent about the practice. They could display a ‘derank’ or ‘delisted’ label to all users.
