Sina Weibo has been asking for mobile phone verification, and the text message was successful. The next day, he said that he had verified it and sent a short message, which was not normal. Isn't this a money scam? I also think it's a deliberate scam. I only log in to one computer, and it says it's not normal all day. Others send verification codes to the mobile phone for verification. Only shameless Sina lets users edit their own messages and send them to it. This is not a deliberate scam. What is this? SMS is money no matter how cheap it is. Besides, I don't know how much to send.
