Unfortunately this looks like the start of an bot vs. humans war. But I've warned about this enough. In any case it will be a long war and maybe distributing rewards too broadly is the cause but who will say that they are willing to give in to some centralization for protection? If the problem gets too bad then more users will switch from steem power to steem and then to steem dollars and ultimately the fiat will win. Don't let the fiat win!
