I think we've got real proof of the power of a single whale now.
I'm not about to tag any whales here, but anyone who's been paying attention knows that one whale single-handedly downvoted several of these posts into the land of no rewards.
I think a coordinated effort of high power downvotes sufficient to at least erase the one consistent whale vote for about a month would probably be enough to either get them to stop wasting their power, or at least slow down and evaluate. And this is just one account, there are countless others.
Is there any benefit to get even minnows to delegate as little as 5 SP to a larger downvoter? This would one way to put power to use without fear of retribution.
I hope there is a legitimate response to your call to action.
