While Twitter announced a permanent ban of President Trump out of "fear of continued incitement to violence" it turns out the accounts of individuals using the social media network to hatemonger against people or groups they deem "inferior", including ones calling for the destruction of the State Israel and Jewish people, continue to spread their message with little or no restrain.
Iran's "Supreme Leader," Ayatollah Ali Khamenei, makes regular use of his account, for example, to threaten Israel, the US, and other Western states.
In a tweet from 2018 that still appears on his account, the "Supreme Leader" threatened to destroy the Israel, writing, "Our position against Israel is the same we have always taken. Israel is a malignant cancerous growth in the West Asian region that must be removed and eradicated. It is possible and it will happen."
Last July, Khamenei published a post vowing to retaliate for the American assassination of Quds Force General Qassem Suleimani in January of that year.
In May of last year, Khamenei reiterated his call to destroy the Jewish state.
In 2014, Iran's "Supreme Leader" tweeted a nine-point plan explicitly detailing means of eliminating Israel.
Venezuelan dictator Nicolas Maduro, accused of committing systematic human rights violations, is another leader of a rogue regime with an active Twitter account, conveying messages in support of communism and hatred of the US.
Media outlets representing the Chinese Communist Party are also known for spreading their message via Twitter. For example, People's Daily, considered the Chinese government's main propaganda apparatus, tweeted last November that "all available evidence suggests that the coronavirus did not originate in Wuhan, but could have reached China through imported frozen food products and their packaging."
Other highly controversial figures such as including former NFL star O.J. Simpson, charged with the 2008 murder of his ex-wife and her partner and sentenced to a lengthy prison term on charges of robbery and attempted kidnapping continue to run uninterrupted Twitter accounts.
Even radical Nation of Islam preacher Louis Farrakhan, widely considered amongst the most vicious anti-Semites in the world, as well as renowned neo-Nazi Richard Spencer continue to make good use of the platform to spread their message.
