Why don't you work on removing the down vote button? Oh that's right, you would lose complete centralized control, ain't that right boss?
Oh the irony when Blurt has a centralized "Coal list" where thecryptodrive can (and has suggested) remove a users ability to receive upvotes on all posts if he feels like it. So instead of a downvote on one particular post where everyone's stake in the community can decide rewards, one central authority can completely disable one person's ability to receive upvotes, effectively a single authority downvoting every future post to $0 instantly.
You really should understand what you are using.
