Since Elon Musk acquired X, formerly known as Twitter, he has received criticism over content moderation policies that allow hate speech. After a recent coding change for X’s artificial intelligence chatbot, Grok reportedly used antisemitic language in its replies. It has since received an update.

Elmo’s verified X (Twitter) account was hacked Monday, leading to a wave of antisemitic, racist and conspiracy-laced posts. Sesame Workshop has secured the account and condemned the content.
