Twitter locked Oliver Alexander out of his account for 12 hours and then later restored the account: Twitter locked the account of  Oliver Alexander, who is an analyst with open-source intelligence (OSINT), according to his Twitter profile. Twitter claimed "[w]e have determined that you have violated the Twitter Rules, so you'll need to wait some time before using Twitter again," according to screenshots. The screenshots also show that the account lock lasted 12 hours and that Twitter left the "specifically for" section of the notice totally blank, showing no reason for the account lock. After some backlash and an appeal, Twitter reversed its decision and attributed the issue to an "error."
