Down votes are part of this system and they have to be. Imagine people uniting and making money just by voting each other out. I'm not talking cents, I'm talking dollars. AND imagine them doing it without sharing anything, just a few words and a $100 post. All the Trending pages are full of them. I'm not saying it would happen 100% of the time, but even the possibility would be frustrating. We would never see real quality posts.
