That guy that is downvoting you was enforcing 'community standards'.
You gotta make the posts more personal and comment on folks so that they know you are here, otherwise the downvotes will continue.
You could set the rewards to burn and still earn reputation points.
The people voting you still get their curation rewards.

When things get downvoted, the rewards go to trending for the most part, so I can't vote your posts until this clears up.
