Johnstone, a self-described“bogan socialist” and critic of imperialism, had over 33,000 followers on Twitter when she got banned - apparently over a Thursday post criticizing McCain. Being both vocally anti-Russian and a critic of President Donald Trump, McCain is a figure popular with both the NeverTrump conservatives and #Resistance liberals. The hawkish Republican has battled brain cancer for over a year.

Johnstone’s tweet said that McCain “devoted his entire political career to slaughtering as many human beings as possible at every opportunity,” according to a screenshot. She then added that “the world will be improved when he finally dies.”

It is unclear what particular Twitter rule might have been violated in this case. Johnstone reportedly said that Twitter described her post as “abusive behavior.”  Twitter does not comment on individual account suspensions.

Over the past two years, Johnstone has made enemies on both the left and the right, for defending WikiLeaks co-founder Julian Assange and calling out propaganda about Syria and Russia. Some Twitterati decided that she’s gone too far with her McCain comments.
