Why do you receive messages from homing pigeons?

The reason why I received the message from pigeons was from my friend. According to relevant information, Messenger Pigeon is a WeChat applet, and friends can send messages through Messenger Pigeon, which is similar to anonymous messages. Pigeons can send messages anonymously without logging in or binding their mobile phone numbers. Pay attention to the official account of WeChat, the assistant of homing pigeon, and click the blue font automatically sent by the system to enter the message system.
