Decentralization comes with the good, the bad and the ugly. There are going to be other scams and farms on Hive, but at least some of us pay attention and bring it up to the community so some of us can act. And this is still with 8K active accounts. What would happen if we would get to 100K active accounts? It would become much more difficult to find these farms and Downvoting let's say 1000 accounts or more a day would be quite costly.
