Received SMS: Amoy members plus WeChat for free! What is the routine?

In fact, I have tried to receive such information several times myself, but I usually ignore it. On the one hand, I'm not going to covet his gift. On the other hand, I'm afraid it will be a trap. For example, after adding this WeChat, if you want this gift, you have to do something. Then if something deceives you at this time and asks you to give an account, it will not be worth the candle. So after I receive these messages, I usually delete them. As for what you are told to add in the official WeChat account, it doesn't matter.
