Censoring on Seeking Alpha

I understand that Seeking Alpha is now censoring Avi Gilbert.  Unless it is for violation of basic common courtesy or some form of personal attack, I am very disappointed.  We are seeing censuring in other parts of our society.  Alas, IMO, historically, no matter how well meaning, it is the start of the death of freedom. It is part of how the Nazi Party rose to power in the 1930's.  And it is how other many other dictatorships operate.  I sure wish that part of every American education was a serious study of George Orwell's 1984.
