Heya, I'm following the downvotes from @trafalgar, he'll probably write a better explanation than me, but long story short, bidbots are bad, bidbots that undermine steem to pump another token (DEC) are even worse. We are targeting it to force it to close (if people who buy votes get downvotes that are as big as the vote, they most likely won't buy again). Don't use bidbots and you won't get downvoted by us :).
