As far as I'm concern, upvoting/downvoting isn't fun, it's an act of public service. I'd be incredibly concerned that corporate entities will have huge incentive to buy fact-upvotes and since there is no limit how many they can use, it would take 5,000 good samaritans to undo the damage of 1-shill with $5.
Basically a deal-breaker to me that the site is that out-of-touch with the problem of internet news. Frankly, I'd like a news site that does the opposite - 1 vote per proven US citizen (no bots, no foreign influencers, no corporations).
