You say that like it needed to happen. Sure some people may be too liberal with their votes. Perhaps though those little stray upvotes to people who otherwise wouldn't have gotten much of anything might mean something. Might even mean a lot. Some people are always going to have an outsized influence in communities. And you cannot have a flourishing community by trying to eliminate that.
I'm all for eliminating coordinated Mass voting. But I think limiting your most active participants is a shooting yourself in the foot sort of move.
