“We’ve observed the emergence of persistent conspiracy theories, alarmist rhetoric unfounded in research or credible reporting, and a wide range of unsubstantiated rumors, which left uncontextualized can prevent the public from making informed decisions regarding their health, and puts individuals, families and communities at risk,” the company said in its policy against sharing Covid misinformation.
People who violate that policy are subject to escalating punishments known as strikes and could face a permanent ban if they repeatedly share misinformation about the virus. A 12-hour ban, like the one Ms. Greene is experiencing, is Twitter’s response to users who have either two or three strikes. After four strikes, Twitter suspends users for seven days, and after five strikes, Twitter bars the user altogether.
Other Republicans who have been suspended from Twitter have complained that the social media company is censoring them.
In January, Twitter barred President Donald J. Trump after the company determined that his social media posts played a role in inciting violence during the riot at the U.S. Capitol. Mr. Trump has argued that Twitter and Facebook, which also suspended his account, were censoring him and said the companies required government oversight.
Ms. Greene was previously suspended from Twitter in April, but the company said it was a mistake caused by one of its automated systems for detecting spam and abuse.
“Everyone knows that’s a LIE, and it was no mistake,” Ms. Greene tweeted after her suspension was lifted.
