Tik Tok private message has exchanged more than 10 messages. What is the decryption mark?

Maximum number of messages sent per day. In Tik Tok, more than 10 messages are sent to each other every day, and an unlock sign appears, which means that in order to prevent users from sending spam messages, Tik Tok sets an upper limit for sending messages every day. When the number of messages sent by the user exceeds 10, an unlock sign will appear, prompting the user to reach the upper limit of sending messages and need to be unlocked to continue sending messages.
