Every system that has ever been made by a human can be gamed by a human. You cannot possibly prevent it 100%. But you can make it more difficult, and by doing so, decrease the probability/percentage of such events.

Just because you can always think of ways how a certain system can be gamed, that doesn't mean we should stop trying to improve things, and just sink into the nihilism that nothing makes sense anyway.

But of course, I'm not that stupid to actually believe that STEEM ecosystem is about quality, fair play and growth.
