FYI, Dan or Ned (can't remember which), up-voted a post for steemvoter once a long time ago. On my account, not steemvoters account. It explained the plan if I remembered correctly, and was a blog post that the steemvoters had voted on.
So, I don't think your assumptions are correct.
iirc, originally the plan wasn't to have users pay with voting on an empty post every day. As a matter of fact, iirc that was in the fine print in your website, and i was the one who first brought to light.
That said, your posts are abuse as described in the white paper. An upvote from ned or dan doesnt change that.
