He currently has the highest reputation on the entire blockchain, which is quite a problem if you think that reputation counts for something. I should point out though, that steemocean shows he is not even in the top 10 accounts for self upvoting: https://steemocean.com/
I can also see that he made zero downvotes during the last indexing period: https://steemocean.com/voter/haejin
