Twitter censors user's post about conflict in Ukraine: A Twitter user shared a screenshot of his censorship notice. He had tweeted: "Ukrainian citizens protecting their city against armored vehicles & tanks with molotov cocktails. #PatHeads #PutThatInYourPipe #ChewingTheFat." Twitter found that this violated one of its rules, but did not indicate which one was violated. The user was required to delete the tweet in order to regain access to his account.
