@haejin, it is due to one whale @ranchorelaxo voted him with 1.34M SP VP several times. This is not a joke, it is evolving consensus or random act. It is an experiment where it was assumed that good whales will counter evil whales. It is hard to satisfy all the biases of human behavior ( circle jerk + vote selling). But it is better experiment than wasting energy equivalent of a country (e.g. BTC, ETH) through PoW mining. The VP in DPoS is incentivized for curation, however, the rules for VP can always be changed in future HF when consensus will arrive for better.
