I don't think this is very necessary. I mean, sure people are going to abuse any tool that you give them. However, people who do that do not actually build the steem power that they need. They don't actually make much of a difference in the money that is distributed. The folks who build quality posts and spend time making good replies tend to actually garner more support. They build more power in the community and their votes hold more sway. While ultimately this does not do anything to discourage these poor quality behaviors, it DOES actually promote thoughtful responses. Over time, you will never make anything by spamming upvotes and saying "Much wow, so thanks" on every post. It is only by hard work that you make your vote matter. Once people realize that it isn't worth their time to do so, they will fade out or start producing. The internet was never meant to squelch the dummies... It was meant only to promote great communication. For my vote to matter, so does yours, even if I think you are ignorant. : )
