I did see this problem coming and when I suggested a proposed solution (vote negation) it was rejected by the very whale(s) who are acting out today.
Thats not a solution. The solution is what youre doing right now -- downvoting crap sockpuppet accounts when they make crap, overrewarded posts. IMO, its long overdue.
The system already provides a means to negate a vote that you disagree with. Casting a vote in the opposite direction.The vote negation thing, IMO, was a cop out. It was a way to downvote bad content without having to sign your name to a downvote.
It was also potentially hugely abusable. What happens when the guy you describe as prone to tantrums decides he doesnt like someone so he's going to take away their vote (which he can do, if theyre a non-ninja, with just a small sub account that he doesnt use anyway)
part of being a leader is coming to terms with the notion that sometimes, maybe even often, youre going to make a call that some people don't like. And youre going to get called a shithead.
