Here, as @transisto shows, the corrupt - unless they are whales - can be flagged.

Not sure I agree with that, I've had flag back and forth with Blocktrades for example, There isn't a single whale that I would not down-vote if it was deserved. The difference is that if it ever happen it will very unlikely result in long term fight, we'd resolved our difference or maybe one of them will cash out and move on.
