Twitter inexplicably censors user for using a common phrase to denote shame: A Twitter user shared a screenshot of his friend's censorship notice. The censored user tweeted "@Saracens Deserved nothing out of that. Embarrassing performance. Hang your heads. That was abysmal." Twitter claimed this violated its "rules against abuse and harassment." The user's account was locked until he deleted the tweet. This is another example of Twitter's shameful AI algorithm.
