"having a one-to-one relationship between real-life people and steemit accounts will greatly help in diminishing the level of abuse because of "portable reputation".
There is no reason to expect this to occur, other than those I have already discussed. Wishing a thing would be is not reason for it to be.
"I have zero ambition for Steemit to become the site that hosts Donaldleaks or Xileaks or whatever."
"... "freedom of expression" is only dangerous when the expression itself is harmful to someone."
If you want a community to be able to speak freely, then you must accede to the reality that some people will speak about crimes and corruption that impacts them. Those things are harm. People are concerned about them when they are impacted by them. They will need to speak about them.
That I did so was why my head was beaten into the sidewalk. I harmed no one. I was being harmed, and challenged it. This is exactly what the whistleblowers did, and what is no longer possible on most platforms, and why Steemit is attracting many users today.
You utterly fail to acknowledge that harm is being done and that the bad actors that do this harm seek to conceal their participation in it, and that can only be revealed where there is freedom of speech.
Either Steemit permits freedom of speech, or it becomes NOTHING but a tool of repression, which I, and many, many others, will eschew. There goes your investment.
Your contention that only expression that harms is censored is utterly vapid, insipid, and not only without value, but is itself a harm to free people. It's equivalent to calling a gag on a rape victim necessary to prevent the rape victim from harming the rapist by calling for help.
That's not an exaggeration at all. It's what you advocate in your vision for Steemit.
