On Copyrighted and Extremist content:
I think it is best for this platform if we let this content exist in it's own bubble by filtering it by default, but not censoring it.
Due to the lopsidedness of the SP distribution it makes it very easy for one person or a small group of people to police opinions they personally don't agree with.
Down-voting will make steem a circle-jerk where only the most sanitary content can be rewarded. How boring will the content on steem be if we start forming down-voting brigades for anything slightly offensive?
Let's not ruin the ultimate censorship resistant platform by policing content we disagree with.
