I had been on Quora since Trump won election. Lots of views and upvotes. My questions or answers never been "collapsed" before ever. Exception - spelling mistakes which I gladly correct (English is my 4th language I have learned).
Last week, while answering somebodies question "why so many hateful comments from Russians", I replied comparing Kremlin trolls to lice in human hair and how to get rid of it. Secondly, I warned Quora if they don't clean up the site, they may end up before senate committee like Facebook and Tweeter.
Those two factors were possible reason for collapsing my answer and warning me of suspending. I was fuming. After couple days I just cancel account all together.
There is chinese proverb: "Man stops being smart minute replies to stupid question"
My conclusion is either moderators are very low IQ (if any) or it really infested with Kremlin stooges.
