I don't want to pay just because people disagree with me though. For instance, I've had relatively innocuous comments get downvoted on Reddit because it's an unpopular opinion. A great way to get downvotes is to find a thread where people are complaining about speed locks in apps and post "studies have shown that distracted driving is at least as dangerous as drinking and driving."
You'll almost instantly get downvoted to at least -5, despite the verifiable truth of the statement.
It would make vote brigading really attractive as well. Imagine if /r/TheDonald users could have caused a financial impact to anyone just by downvoting their comments. Reddit would have been a nightmare.
