Yep. After eight years on the site I finally had a comment removed, and my response to dang to discuss it was completely ignored. Made me feel dumb for even trying.
In other words: People who think HN moderation is all fine and dandy only believe so because they've never had the audacity to post an unpopular fact or opinion.
It's also possible that I saw it and was too exhausted to look back through all the flagged comments in the thread, identify which ones were explaining how AMP works, and see if they had been flagged correctly. That takes a ton of energy, which is not always available when the rest of the site is clamoring for attention and in varying degrees of onfireness. One thing you can do to increase the odds of getting a specific response is to include specific links to the post(s) you're worried about—that makes it an order of magnitude easier. I certainly appreciate your intention to defend fellow users who are being mistreated.
But I think if I had seen your comment I would have replied at least to say that I believe you that your intention wasn't to downvote-bait.
