Twitter censors user for a joke about Joe Biden: A Twitter user shared a screenshot of his censorship notice. He tweeted: "@POTUS Go fall off a bike." This was following the incident where the president had actually fallen off his bike. Twitter, however, saw no humor in the tweet and labeled it "promoting or encouraging suicide or self-harm," according to the screenshot. The user's account was locked until he delete the tweet, and he reported having his account in a read-only restricted mode for 24 hours, though this could not be confirmed.
