Considering the OP is calling into question why this person was booted from some social media, posting lies about public hospitals and their staff during a pandemic seems a fair reason.
Shame the posts on Twitter remain and a shame Twitter themselves have not taken action.
"A source just gave me the following information. A hospital in Wales, Nevill Hall in Abergavenny, has 250 beds. 200 beds are empty. The surgeons are bored & pass much time on the nearby golf course.

Have a great day / life etc.
