Clearly people got tired of AOC dunking on them.
Joking aside, I guess it's one way to counteract people gaming the system with burner accounts and whatnot, but it also makes it harder for people to notice how widespread the problem is on Twitter. I feel like a high Like/RT count also means people will be less inclined to dunk on/quote tweet them, so it might exacerbate the viciousness on the platform.
One metric I never understood was the Tweets count, because it doesn't distinguish between replies and public tweets. At that point, a high tweet count might just mean you interact with people without clogging everyone's tl.
