It happened to me a few days ago. The article I posted was about the cop in AZ who was told not to pick up his daughter from school in uniform (because of his sidearm).
I noticed the next day it was a dupe but under a different headline. Anyway, within minutes of posting it somebody posted a comment: “go to hell”. I have no idea nor much care what that was for or about. 5 minutes later the article and comment was gone without explanation.
I though it was extremely rude to do that without an explanation.
I wasn’t logged off though - just had the posting deleted.
