If you ever wondered why 99% of the world doesn't do this beyond just moral reasons: https://en.wikipedia.org/wiki/Brutalization
Social platforms must remain neutral carriers, not arbiters of truth and morality. Unless it’s governed by a democratic process.
Until then slap an 18+ tag on it and move on.
Your comment about LBTQ+ is interesting. That is most likely blocked in backwards countries where things like that are illegal, or various platforms would face consequences in those jurisdictions.
Livestreamed or not, this is immoral and Australia are quite right to try to block it. All countries should be seeking to do the same.
The purpose of the live-stream *is* the ugly thing. It is not a retribution from the state meted out on the perpetrator. It is propaganda. It is similar to ISIS beheadings.
I hope you did not mean that the propaganda is a good thing in this case.
