HF19 may have tipped the scales a little too much. I've always been excited about giving people a few $ per post. Imagine my surprise when my vote was worth $20 usd! Wow!!!
That's real money at 10 votes a day. So what prevents people from setting up spam accounts and voting all rewards to themselves via proxy? I realize they could do that with lesser amounts, but it's not worth their time.
In short, I think we overshot the mark on this one.
