Yeah, he is not actually targeting authors who post in the community. He actually sets downvote on the trail that follows the blogging-team. So if we vote the post of authors, the downvote comes by.
I get the downvotes in post I make in other community because of the person downvoting the curation trail.
Thanks for your explanation. Can't the voting trail remove someone who's tagging along just to downvote?
I don't think that's possible. Only when the person wants to remove the trail himself.
