He did the same thing to me when I gave away 100 STEEM, he zeroed the post (as well as many others).
He claims to "upvote himself only to counter the downvotes" but has been upvoting himself since day one, the only time he doesn't is when he is downvoting.
He claims to only downvotes people who downvote him, but I never downvoted him and he took thousands from my account downvoting.
What he says, and what he does is very different.
Add in the fact his "TA" is comically bad he is just part of what will destroy Steem in the end.
