The Grumpy Cat thing is another issue entirely. My problem right now is with the bot that ate my money. If Grumpy is of the opinion that a post isn't really worth what the payout shows and downvotes it, that's his prerogative. As annoying as that may be for the post owner.
E.g. I'm a poor pisser renting a Mercedes to impress the girl, and she could get in the Lamborghini of the guy who owns one instead. Tough titties. That doesn't mean the car rental place can take the wheels off the Mercedes after they have processed the rental agreement and my credit card.
That said, I agree with you: There should be a consensus on bot rules - or no bots at all and a better promotional mechanism instead.
