Twitter censors user for ridiculous reasons: In another case of Twitter's terrible AI algorithms gone wrong, a user shared a screenshot of his censorship notice. The user tweeted: "You were pulling the top off of a Montblanc mechanical pencil to refill it, and punched yourself in the nose? I know the pain." Twitter's AI determined that this constituted a violation of its "rules against promoting or encouraging suicide or self-harm." The user was required to delete the tweet in order to unlock his account.
