"...drive them from the ecosystem."
How? I used to think some of your statements were a bit harsh, but then I saw today that @steemit took out over 1M steem. Now I think you've been overly gentle. There's still no mechanism by which I can see a way to gain control over witnesses or bidbots. Stake has all the power, and the ninjaminers have more than enough stake to just flag any complainers into dust.
I'm just waiting my turn =p
The only hope we have is that the bad ninjaminers are corralled by the other good whales, or that interest in what steem could be persists until the bad actors powerdown and leave.
Otherwise, and we are just waiting for the last sucker to buy so somebody can shut off the lights.
I think some of the current dupes will be far harsher than what I've been, once they get clued in.
