Strangers send me text messages, and I reply. Is it harmful to me?

In fact, it is harmless for strangers to send you text messages, because there are many strangers in WeChat now, because they don't know who they are. Sometimes he listens to records to see if zombie fans sends you messages. If you send something inexplicable, then I suggest you blacken this stranger and don't contact him again. Maybe he is just a routine. Maybe he is doing some kind of WeChat business and wants you to buy something. In fact, for strangers, it is better to ignore them.
