I love your idea!! Finally I read a good post about helping people in Steemit in a right way. The downvote is the greatest idea I've read and I would totally support that. I have seen people who flag some post but they leave a comment explaining why they flag the post, putting in the comment that if the user changes what did wrong then they take away the flag in the post, and that's a good way to use the flag but I really hope the downvote button becomes a real thing. Good post, greetings!
