I think the danger in dunking is in the fact that a QT is a QT regardless of what the content of the QT is. Screenshots definitely help with this.
Replies also feed the algorithm. Ted Cruzs whole Twitter existence is this.
Dan Pfeiffer, former Obama comms director has a chapter at the end of his most recent book about it. He argues as Edman does, with screenshots being better that actual rt or reply but best to ignore altogether. I have changed my Twitter behavior a lot after reading that from Pfeiffer.
That said I'm not a dunk champ like Greta... but I will admit I had never heard of Tate before she murdered him and now I do... and I'm pretty sure his follower count spiked from the interaction. He's a really bad dude.
