I think he set his bot in the early days to people who were posting good/decent content. Seems like a "set it and forget it" perhaps? I don't know the whale in question and I am not sure if anyone receiving these votes does. I think he just turned his money printing machine to autopilot. If downvote's come my way to counter, so be it (reputation be damned). I have enjoyed the votes and I feel I make good post, but it is what it is... People are going to do what they will with their stake and I am alright with that , it takes all kinds.
