I wonder what idiot PR “expert” came up with the idea of screaming “Shame!” as a tactic? It just makes them sound like the world’s worst evil parent. The kind where the kid escapes out of the window in the middle of the night to run away from home.
When I was a young child (I'm In my 60's) my grandfather used to say "shame, shame, double shame! Everybody knows your name! " when he thought I was misbehaving.
Even then I thought it was silly.
