Andrew from Toronto: "hire disinterested moderators to review "uncivil" comments... suppress viewpoints..."
I think that does happen but at least when a public reviewer does it then it leaves a visible trail. I am more concerned with a dozen posts getting "disappeared" from the system with no trace and finding my account restricted because of "too many uncivil" comments even though I had only ever had one comment actually and (wrongly) marked as uncivil. As you note the paid staffers need to be disinterested, unfortunately it is clear that at least some of them are not.
