I think there should be something like this....If a post gets enough 'flags' then it's seen as abusive and hurtful for the blockchain. But because we're stake based, a single account can disagree with ANYTHING about your post, and send it off into the wastelands lol
Majority rules and all that, if there is enough 'downvotes', then a post should be looked at as abusive and hurtful....Not because one person disagrees with it.
But alas...I dont spend much time thinking about these things...I prefer the upvote culture :)
