I've never flagged, so I didn't know a box popped up. I suppose I'm suggesting tweaks to that box and how it works - forcing people to say why they've flagged and have it displayed.

All those technical aspects are a bit lost on me. I've never posted using those other ways in - can people upvote / flag through them as well? And you're saying that my suggestion could only be enforced on those voting / flagging directly through the Steemit interface, and not through others?

I wasn't necessarily thinking it would stop people, more that it would make them accountable to a certain level.
