Yeah - one thing I've noticed with some forums is that the addition of the "like/dislike" buttons (some have even more reactions available) greatly INCREASES the signal to noise ratio (I mean makes the forum have more signal, maybe I said it backwards) because the "me too" posts and the "fuck off" posts are reduced, you can just hit the button instead.
Some streaming platforms have a button you can hit that makes party emoji or heart emoji or whatever appear in a stream from the lower right, that's a similar thing which helps with cheering so you can then combat flooding.
I've observed the same with Matrix and Discord. It reduces noise to the point that while "fuck off" would call for moderation in a lot of contexts, reacting with the middle finger emoji usually doesn't even though it has the same meaning.
