I've been self-voting on any of the posts that they are down-voting. They are the only posts that I upvote and I don't do it till they do.

In fact, part of the reason that I am powering up is to have more STU so I can counter his affect 100%. Currently I'm relying on the curation reward from the vote to even things out.

When I have enough STU, I will start self-voting at the 6 day mark if they decide to hit the post.
