I noticed how highly voted the post was, so I went in to read the comments for a couple of minutes. When I hit "back" to return to the main page the post had mysteriously disappeared. I found it fleeing down the second page, past many stories which had lower scores and had been lingering for much longer periods. It was very surprising.
These current-events climate stories are the most important pieces of news on the site. If the moderators are deliberately nerfing them (ETA: or exploitable algorithmic policy is allowing them to be nerfed), I find that extremely terrifying. I hope it is not the case.
