Twitter censors user for making a joke about the possible side effects of the COVID-19 vaccines: A Twitter user shared a screenshot of his censorship notice from his alt account. The user, in quote-tweeting a tweet announcing that booking was open in Ottawa for fourth COVID-19 vaccinations, said: "'Haven't had a blood clot or heart attack yet? We can help..." Twitter locked his account until he deleted the tweet, then placed his account in a read-only restricted mode for one week, citing a violation of its policy on "spreading misleading and potentially harmful information related to COVID-19."
