Negative Curation Rewards?

This was an idle thought that crossed my mind this afternoon... At the moment, there has been quite a great deal already written about the ideas (pro/cons) of auto-voting and vote selling, and how that results in behavior that is perhaps not beneficial for the ecosystem, or at the very least are the unintended results of the underlying economic incentives for curation/author rewards

Most of the focus so far (and given that I'm not really an avid follower of the internal debates on the mechanics/economy of the Steem ecosystem) has been on the reworking of the curation/author reward balance and the addition of a down-voting pool that won't eat into your regular upvoting "allowance".

However, as far as I understand it, this doesn't address what I see as the central problem with voting. The problem as I see it, is that there is absolutely not real economic incentive to actually care where your vote goes! Of course, there is a positive economic incentive via the curation rewards... but if your vote goes towards terrible material or plain scams, then there is no economic penalty. You essentially get zero rewards, but that doesn't really matter in the end as it is where you started to begin with!

In fact, this is a problem that I see with curation and upvotes for usage models. Everyone is all too happy to give out sweets and candy, but very few people/groups will follow up properly and do more than remove a vote (or promise to not vote in the future, aka blacklist). This leaves a potential scammer sitting with no negative consequences for bad actions... at worst, it is zero consequence!

So, I would like suggest the idea of a "negative Curation reward"... in that, if your vote goes to a post that garners a total negative vote (hidden or rewards less than zero), that you actually lose stake! This would have the immediate economic effect that people should really care where their votes actually went... however, there are more than a few unintended consequences I'm sure... first and foremost of which would be the weaponising of the downvotes to be even more nasty than they are at the moment.

However, this is a floating of an idea... of course, I'm not foolish enough to think that such a simplistic idea would be a fix for everything with no consequnce. However, the general concept that stake can be not only gained but also lost (something that doesn't exist at the moment...) could be a possibility for exploration? The reason that I've used a Palnet tag is that perhaps that this is an idea that would work better when the difference between rich and poor isn't quite so large!

After all, in the real world, we have both positive and negative consequences for our actions... it seems strange that here on Steem, we only have positive consequences, or larger positive consequnces... and at worst... zero!
