(Apologies if you've commented on the following already, but I've not seen it.)
The most concerning growing trend I see is comments that don't violate any guidelines, but are flagged to dead.
I'm not talking about posters that are shadowbanned, but about comments that engaged thoughtfully on a topic but the rest of the thread disagreed emphatically with.
I also don't even mean controversial takes on hot-button issues like vaccines.
Just plain old bucking the trend in a thread about AI, transit, housing, layoffs, etc.
I've been browsing with showdead on for as long as I can remember, and I'm seeing this accelerate. Comments from folks both you and I respect as high quality contributors here.
I don't know what the solution is, but it discourages me (and I'm sure others) from having the kind of thought-provoking dialog I've gotten used to reading here for the last 15 years.
