Haha. Id hardly call him a sociopath for downvoting you.
"Justice" is only served if you done something wrong. Did you ask yourself what you might have done wrong?
There must be a reason given.. I suspect what it is but you can always ask him to know for sure.
All of us here are stake holders and when a downvote drops thats a means for us stake holders to make this platform better and protect our investment. That might not always be the case but the majority of times it is.
