As you can see from the screenshot above, my 100% downvote only took the potential rewards self voted down to .03 Steem (Apparently half of what you can achieve). It doesn't matter that I cannot solve the problem myself. It matters that I do what I can. I'm not sure that this botnet can be outvoted by all minnows and dolphins combined. I actually suspect it cannot, because the stake was derived from the original ninjamine, and has been continually used to extract rewards via self voting since. However, the quest for ROI this user is on will impel them to change their behaviour long before their SP is outweighed. When it is reduced in profit more than it's harmful behaviour benefits it, it will either change behaviour, or prove incapable of reason.

I expect the strong profit motive will induce change in behaviour.

I do what I can, and that is all I can do. Do what you can, as you reckon is going to impact the environment in the best possible way. Thanks for the additional confirmation of this accounts harmful nature.
