NEW YORK — That soothing sound that Mr Gary Cavalli hears emanating from Twitter these days? It is the sound of silence — specifically, the silence of former US President Donald Trump.

“My blood pressure has gone down 20 points,” said Mr Cavalli, 71, whose obsessive hate-following of Mr Trump ended for good when Twitter permanently barred the former President in January. “Not having to read his latest dishonest tweets has made my life so much happier.”
