I very much agree with you; I think it is weird to celebrate steemit as an open platform, but then call for some kind of police.
Freedom means more responsibility for each of us, and everybody should vote responsibly, but also flag responsibly. If this was becoming normal (NOT whalewars), and flags were something normal (NOT whaleflags!), this platfrom might pan out itself pretty nicely.
So even though I'm scared, I'll try that. My rules:
Small flags (-0.01) are good to use if you disagree with content, opinions or language; strong flags should be only used if a post/comment is unfair or damages the platform or other users on it, and they should be preceeded by a warning.
