It is of psychological nature... He is jealous of others being successful on the blockchain. He has mobbed so many accounts off of Hive, that they cannot be counted anymore. Little Marky was probably a playground bully, when he was a kid, repeating his behavioral patterns here on the blockchain with big stake... Instead of getting a life, he seeks the attention here... To cover the whole thing up, he will start telling you something about too much earnings, a 'milked' reward pool etc. blabla... The truth is: He himself milks the reward pool! To be clear: It is OK, when HE does it! Hey, after all... It's Marky... 😉
