People are having their Twitter accounts automatically suspended for tweeting the word 'Memphis'. Dozens of users have reported having their posts almost immediately removed and their accounts blocked for sharing the word. And it appears that those who have dared to tweet the name have received a message informing them they have been locked out for 12 hours. Where Memphis' name had been, it now reads: "This tweet violated the Twitter rules." It's not quite clear why it is going on, and Twitter are yet to comment on the bizarre happening.
