Want to see a good case of abuse? Check out the wallet of @rolan555. You'll see that many Hive accounts sent him Hive. And if you look at them, you'll see the massive amount of money he farmed on the network with multiple accounts.
Someone recently said that there are no low-quality posts, only bad curation. And I think that person is right. Some curators indirectly lined Rolan's pockets with their poor curation.
You should check the wallet of @stickupcash; you might discover that Stick also lost money with BRO. You'll see 1307 BRO tokens. Also, a few LGN. He had a few Hive tokens there.
