The question is why doesn't STINC do something about it?
I'm all for self-governing society where social trends direct the flow of power, but when power and reputation can be bought, the umbrella (STINC) needs to lend a guiding hand to steer the ship in the right direction.

Maybe the answer is to have community backed moderators, almost like the Witnesses where the community elects a number of moderators who can help guide the system, not for rewards but for fairness.
But then again that's also corruptible and can get used for evil.
