The stats are skewed. I usually upvote myself with 99% of my votes.
More seriously this post was really interesting to me and the tone of it, at least the version I read, was presenting the stats in a pretty neutral manner.
Abusive selfish-voting and its perception are an interesting issue. We'll see out Steem evolve from here and where we take it.
Just to be clear, I'm not accusing anyone of abusive selfish voting and bigger % of self-voting isn't necessarily equal with abuse...
but maybe you do vote for others much more than yourself. I always upvote my own post, but I don't vote for my own comments (rarely). I do spend a lot of time voting for others, that is why I"m at 4%.......which I think is reasonable. I think when someone has the 99% of votes going to themselves, well then that is really problematic. It's interesting data to look at for sure.
