It's hard to understand your stance on downvoting, but from what I can tell, you think everyone who downvotes should just downvote and move on without commenting. It's funny because every post I have seen about downvoting has said the opposite; "Don't downvote just because you disagree" or "If you downvote, post a comment as to why"...
I say everyone should stop trying to dictate how other people use their software and stop complaining that "everybody else is doing it wrong"™️. If you have a problem with downvoting, I think you can join an instance that has it disabled.
That is exactly what I thought of when I read this. Why would Lemmy implement such a seemingly obvious bad feature and become 4chan?
Also, the claim that this would prevent bot accounts is way off. Bot accounts still need an instance to register on anyways. The thing is, anyone can spin up an instance at any time All this "feature" would do is let them hide...
Great post to demonstrate how some ideas might sound good to you, but are actually just bad, lol.
